I haven't done an LO since the Japanese and the home or something that reminds you of home challenge (a long time). Got really swamped at work and just not motivated to go back on Photoshop at home. Anyways, not a big animated gif fan but this is a good example of using animation. I do web work and just hate animated gifs. If you want to animate, just use Flash... that's my thought.
Anyways, haven't tried this but I think it's a photoshop and image ready function. You put your photos in different layers and then jump them over to IR. Your animation doesn't have to be pictures. If you don't have photos in sequence you can use a flower or button and on each layer make sure they are in different positions. Think of yourself making a cartoon... sequence by sequence. The IR part is the one I'm not so sure about... I think it's like movie making time in iMovie, Premiere, etc., you create the timeline each layer at a time and bla bla.. the last part came out of my butt, it might not be off but if I have time tomorrow I'll make a video tutorial. Well, after I figure it out of course
PSE... doesnt' that come with IR too? If yes, you should.
