Quote - what program do you use to re-assemble frames?

     Use a video editor, Flash, or GIF editor.  I sitll use ye olde GIF Animator 5 from ULead/Corel, SwishMax Studio, Adobe Flash CS4, and ULead/Corel VideoStudio 11.

     I think that some versions of both PhotoShop and Paint Shop Pro came with accessory GIF compositors.  Animation Shop came with Paint Shop Pro;  ImageReady came with PhotoShop, GIF Animator 5 came with PhotoImpact (and was also available separately).   So, you may have a GIF compositor without realizing it.  Look in your installed programs for such, and/or see if there's a button/command in PhotoShop or Paint Shop Pro to open the GIF compositor.

     There are almost certainly lots of others of which I'm unaware.
