Tiff to Jpeg conversion

Hi Group, Can anyone suggest me a tool for converting Tiff image to JPEG image? Currently i am using the GD library for manipulating images and i didn't see any function which converts Tiff image to JPEG image. I notice Imagmagic support this feature. Please let me know if anyone has any idea about selecting the proper tool. Thanks, Hardik __________________________________ Do you Yahoo!?
