ziggy - have you found any more about it - its ridiculous that you can have pretty good animation presets and create great looking flash animations that than you can't do anything usefull with.
Bob - there are lots of other proper tools for this however i em not able to find preset animation palette in photoshop and i'd love to see how long will take you to animate words disapearing in a puff of smoke in photoshop. It took me 30 seconds in indesign. Also as i have poster, flyer, pull up banner design in indesign already with all fonts colours and style for the campaign why should i need to recreate the whole design in photoshop to make elements on the page fade, move and disapear in a puff of smoke?
This works for some animated gif styles....
1: export a pdf from Indesign with all the pages as the frames you want
2: set up a psd to the same size then place linked pages from the pdf into it and set the timing for each frame
3: export as animated gif
this way you can edit the artwork in indesign and when you save a new pdf it updates updates the psd
hope that helps
