I created a wee animated gif a while ago but deleted the original Photoshop file (CS3). I need to resize the gif from 100px to 70px for an avatar. When I've changed the image size in Photoshop (it doesn't show the animation frames), it removes all animation. Is there a way around this?
Split the animated GIF first into its animation frames via some online tool (GIFerator for example) or with Image Ready (if you still have it), then load all frames as layers into PS and resize the file as you like. Then do/time the animation again (PS or Image Ready) and export the new version.
