ImageReady can this also, one of many methods is to simply have
tghe appropriate images in a folder, open ImageReady, goto ‘File/Imort/Folder As Frames’. (Best that the images are the same size for consistancy)
ImageReady will proceed to add each image per frame in tha Animation Window.
Tweak the animation as per other palaette options, in your case particularly the time delay in between frames.
Once tweaked to your liking, File,‘Save’, to save the native .psd file.
Then ‘File/Export/Original Document’, and from ‘Save As Type’ list choose QuickTime. Choose your desired compression and codec options at the next prompt, then done.
hope that helps
