Converting GIF to SWF using Flash CS4
A typical ballache… You want to use one of the cool loaders from http://ajaxload.info/ in your Flash/Flex apps, but it only generates a GIF file… So you’ll scour the net for a GIF2SWF application and you’ll undoubtedly come across a few, but you don’t have to look any further than Flash CS4 – surprisingly!
All you have to do is open a GIF file in Flash CS4 and it’ll automatically pull it apart and convert it to frames, which can then be converted to a SWF file 
Hope it helps you at some point!

Hey, why use CS4, when you can use commandline tools :
Check gif2swf from http://www.swftools.org/

Hi Eric
Using the command line tool doesn’t always work so well… I did try that initially but – if memory serves – it messed up the transparency or something fatal like that.
