Converting a JPEG to a GIF in ASP

Does anyone know how to convert a JPEG image to a GIF in ASP?

Thanks.

Reply to my own question (in case someone is ever wondering the same thing):

download ImageFile Object from ZmeySoft
http://products.zmey.com/

actually i'm not sure if you can actually convert formats with this component. but you can extract image width/height info, and turn's out that's all i needed!

cheers
