File Filtering

[Cloudski]

I was wondering how you would filter the files types, (ie: .jpg/.gif/etc) so as to only allow certain types.

Thanks for any help in advance! :thumbsup:

To check if it's an image, use
getimagesize($imagefile); If that returns as false, then the image uploaded wasn't a valid image file.

To check image extensions, use:
