Step 2: Sizes
Step 3: More sizes
You need to:
~make it the maximum size
~Colour mode - RBG
~background contents - transparent
Step 4: The animating
On the keyboard press: Ctrl+a, Ctrl+c
Then click on the transparent image
On the keyboard press: Ctrl+v
then close the original image
Do this with all others, you should get a new layer for each image. If not create a new layer per image as these will become the frames of the animation
Step 5: The animating 2
At the end of the pop up window click on the arrow with the lines and click 'make frames from layers'
Set the timings. I found that 0.5 is the best.
Put the loop on forever.
Step 6: Saving
To check it works open the file in an internet explorer.
Step 7: The emoticon
Give it a keyboard shortcut. and (if you want) a name. Then click OK. It should then appear in custom emoticons. I made the first one and borrowed the next 2 from a friend.
