Animated GIFs
are a way to show several pictures in row so that they form a kind of slow-motion film or video. in 'real' film the still pictures change so rapidly that our brains conceive them as 'moving' picture. in animated gifs the consecutive pictures follow each other so slowly that we see them separately.

NOTE: the perceivable changing from one picture to the next may make an uncomfortable impression in the viewer, especially if the pictures differ considerably from each other.
this may happen especially when the difference in the light levels of the pictures is large or the change in colours between the pictures is large. if in addition the pictures will also change quickly this will make the GIf-picture flash and flicker in a very unpleasant way which may lead to migraine or nausea in the viewer. in some sensitive people this may even trigger an epileptic event.
therefore the GIFs must be made very carefully, choosing pictures which don't differ too much from each other and setting the speed of their changing slow enough.
if in doubt whether the speed of changing is too high it is better to choose slower speed.

in the following i shall collect in one place descriptions of how GIFs can be made. these description have already been posted in different place in the Technical questions topic. i hope that it will be easier to find them here.

Making an animated GIF with PICASION

here's the address of Picasion: http://picasion.com/get-photo/
it's really easy to use: just add pictures. registration is not needed, neither a host for the animations. in the pictures below are shown the things you can and need to do.

add pictures in the 'image slots' 1, 2, 3, ... from your PC-file (it's practical to put the pictures in the same folder because Picasion will remember the folder that was used). you can add more than 3 pictures if you click "Add one more..." (black arrow). maximum number is 10 pictures (which is sometimes too restrictive).

then you can select size of the GIF by clicking the row under "Size". 450 is largest and that is not very big so i usually use it. i think that the default size 300 is too tiny.
Image

then you can select how fast pictures change by clicking the row under "Speed" in the picture below. i prefer "slow" especially for pictures which differ somewhat from each other, because then the gif will not flicker much and it's nicer to watch. the more different the pictures are from each other the slower the gif should be. if in doubt about the speed it is always better to select slower.

Image

finally click "Create animation" (or enter) and soon the gif will be ready and you'll see preview. if it is not ok, then you'll have to start over from beginning. if the gif is ok click on the second line to get the direct link to the gif and it will turn blue. click ctrl-C to copy the code and then just paste the code with ctrl-V in your post inside img-branckets like this (i've removed the outermost brackets):
img]http://i.picasion.com/pic79/32c723e1c6abda6599a143e502e38277.gif[/img

and here's the gif in action. the size in this example is 450 and speed is 'slow'.
Image


Image
here the size 450, speed normal (500 ms = 0.5 s)

Making an animated GIF with The Animated GIF-maker

this GIF-maker can be found in this address: http://www.myspacegens.com/handler.php? ... matedimage

what's irritating there is that they have pop-up advertisements so you'll need patience to close those windows before you can proceed.

the use is rather straightforward. in step number 3: to "upload pictures" first click "ADD", then browse your files and select your pictures, then click "upload". when uploading is finished click "OK" and then "SUBMIT". (before submitting you can fix the speed to you liking in step number 2. their default speed was too quick if i remember right.)

after some processing the GIF is ready. then you'll need to download it to your computer and then upload it to some photo service (e.g. in the Bucket). from there you get the picture code which can be posted here in a mail.

the whole GIF-making process with the GIF-maker is more complicated than with Picasion but there's the advantage that you can submit a maximum of a 100 pictures! the default picture size is also larger than the max-size of Picasion gifs, which is an advantage, too.

here's an example of a GIF made with Animated GIF-maker.

Image
pictures by Alice, taken on Dec 5th at about 9 am.
size normal, speed slow (1000 ms = 1 s)
in retrospect the speed here is too quick for my present taste, though i have used slower than their default speed. the seal looks almost hyperactive. :mrgreen:
if i made this GIF again, i'd use 1.5 s or even 2 s.

aita has found yet two other GIF-makers. thank you aita! :thumbs: :wave:
the first GIF-maker which she writes about below is the same as i described above.

Photobucket - the maximum limit is 25 MB. once my 90 images - exceeded the limit. (So, PNG images can fit in a lot less than the JPEG images.)
http://www.myspacegens.com/handler.php? ... matedimage
This website is good, you can EDIT the gif. Just I chose smaller size and it was the right size for Photobucket.

My favorite is (the fastest and most convenient) http://makeagif.com/
there 20 images at a time.
Size: Biggest Cropped - almost full screen. Size 800x450 gif - looks like 800x600 image

Margossa commented the second, the MakeAGif.

I use makeagif.com too.
I use http://makeagif.com/ because this program is very easy to use.
1 step - add pictures (from "my computer", no need before upload pictures to Photobucket or Picassa or other picture service) after push "continue" button
2 step - create a gif (you can change speed and size pictures (I use 800x450 pixels) and animated gif is ready.
Now can choose a link which can copy to post (It is below animated gif on the website).
When I have a lot of pictures I divide for parts each of 20 pictures.

Making animated GIFs with MakeAGif

you'll find it here: http://makeagif.com/

this is a straightforward gif-maker which aita and Margossa have found. no registration or signing-up is required.
i made a gif of how to use this gif-maker. :D
here the speed of pictures is 7000 ms = 7 s. i hope it is slow enough.
Image

here's another sample.
Image

i think these gifs can be posted directly on the board, if they are made slow enough. i tried first 750 ms first but changed to 1.2 s. i think that slower speed is always better than faster, especially if pictures differ from each other. here i didn't change the size of pictures so they remained original (width 768). maximum number of pictures is 20. that should be enough for most purposes.

i changed width to 500 and left height open ...hmm... no change. :puzzled:
maybe the height should also be given but then one should calculate proper height so that the ratio will not change. too complicated. i guess it's best to resize pictures with Paint (or something) so that the aspect ratio is maintained before making the gif.

posting the gif is simple: copy the code from the "Message board"-box when the gif is ready and then paste it directly in the message here.

today i tried another Gif maker called GIFMaker.me.

clever name for a gif maker and it can be found here: http://gifmaker.me/
Image

it is very simple to use: first click the upload-button and select the pictures from your computer.
then select the parameters for your gif on the right side panel (see picture below).
Image

don't change the aspect ratio ( the ratio of width to height) of the pictures or otherwise the pictures are going to look funny. the maximum size for pictures on this forum is 800 width and 600 height, so these measurement should not be exceeded. either select a suitable percentage or give fixed pixel measurements. both width and height are needed.you can find the correct measurements using for example Paint to resize one picture to correct width/height or percentage.

then select a suitable animation speed. usually it is safer to select a slow speed, especially if pictures differ considerably from each other. if pictures don't differ much then 1 s to 1.5 s is ok. 1000 ms = 1 s.

when selections are ready click Create GIF animation below the control panel. when the gif is ready download it to your computer. then you'll need to upload the gif to some photohost like Photobucket. copy the image code of the gif in the same way as you copy the code of an ordinary single picture and paste the code in your post inside the img-brackets in the normal way.

below i have replaced the inner ] and [ with } and { so that the format can be seen.
[img}http://i561.photobucket.com/albums/ss54/anmaelo/Kotkas2015/Juras-Erglis2015March/J-E2015-03-02/SwansInLoop2.gif{/img]

the result:
Image

the advantage of this gifmaker is that it allows more pictures in a gif then MakeAGif where the maximum number is 20. the maximum number of pictures is 100. the disadvantage is the slightly more complicated procedure of downloading to pc - uploading to photohost before one can post the gif. from MakeAGif you get the gif's image code directly.
