I am going to be running a competition on my forums this weekend and to enter users must upload a picture template to the post.

My question is, to make it both easy and fair, I want users to upload image thumbnails only to the, and not full size images.

I have looked though the AdminCP and can not seem to find an option for this. Can someone tell me if this is possible and how I go about doing it.
