Title: Validate upload

Hello,

I overload the validate() method to restrict uploaded file to real images (manageable by engines) and introduce MIN_WITH and MIN_HEIGHT to prevent uploading to small images

default is 1x1 that also permit too restrict invalid image for graphickmagik that load everything without complaining but return size of 0x0

Cheers,
