[wp-hackers] Is there an image post-upload hook for post-processing images?

[Bjorn Wijers]

Hi,

I'm probably overlooking something, but I can't find a hook which will 
be called after uploading an image. I would like to process uploaded 
images further. In my particular case I would like to process one type 
of featured image further by pixelizing it and blending the colors.

Any help much appreciated!
