i made an image uploading script which then creates thumbnail. it works perfectly except when user upload jpeg via internet explorer. rather than sending image/jpeg as image type, it sends image/pjpeg (note the p in front of jpeg). anybody know how or why this happens? thanks.

Yeah, it depends on the way the image was created. Some programs create the images a little differently and ie sends the mime type differently. I try not to accept most information (especially regarding mime types as that can be modified by the end user) as truth. Normally I'll accept the file and then use the MIME_Type pear package to check the mime type:

http://pear.php.net/package/MIME_Type

Good luck and enjoy!

Hello,
This is not an error/bug in ie.
Pjpeg is a valide image extension, and it means Progressive jpeg (this means it can be streamed and displayed while it is loading.)

You may also search google for it

I hope you will find a solution, if there still one.
