Hi

I don't think file Extensio would matter much.......I mean you can make a .gif file just a File(test.gif ro just test) without Extension and open it in Explorer it would Still Work.......Convert it to any other file extension that is not currently in use like pic.soda and it will still animate in the IE........it's just that a few file extensions are made to behave differently for example if you make a .gif a .htm and open it in the IE it wouldn't work......it would make IE behave it would do with a Htm page..read it's content........i mean give a gif any new extension or any file extension except those like .exe, .dll,.htm etc it will still work......

And AO Converting it from .gif to jpg i am with valhallen ..until someone gives a better reason e.g mnstgrl...............and Firefox is showing it as .jpg and downloading it as .jpg

and Never Trust Internet Explorer with Picture File Formats.........try this trick it will make a .jpg download as .bmp in Internet Explorer........open any web page containing a .jpg picture.....let the IE window open .....Goto Tools--> Internet Options now in the "Internet Options" Dialog Box........Press the Three Buttons First "Delete Cookies" , "Delete File" ,"Clear History" press ok rhen return to the page contaning the .jpg picture ....now try to save the pic to your computer and see ...it would just let you save the picture as .bmp........
