What is the complete list of valid file extensions for images?

Question

And the images I'm referring to are the ones that can be embeddable in a web browser not .tif, .psd, etc.

So the only ones I'm aware of are .png / .jpg / .jpeg / .gif / .bmp

are there any more?

Reason why I need this info is to only allow valid images to be uploaded in my php file upload script.

Answer 1

you can do what ever you like, its all about the headers, and the information inside the actual image that determines the type. (mime-types)

hence why <img href='http://site.com/image.php?name=file'> could actually render an image
