Great points, and I figured as much would be needed to 'rule in' acceptable items
do you think that the browser mime type would be sufficient to 'rule out' items as a preliminary check?
ie: if it passes the mime test, do a size test, else don't bother
or, would that probably toss too many good pictures?

2 - i've noticed a type of "image/jpeg" "image/gif" "image/png" for uploaded file types. can this be relied on to any extent?
I wouldn't. You're relying on the browser to supply a proper MIMe type, which IMHO is not the best place to put the burden.
Personally, I use Image::Size::imgsize() (see CPAN) for this. It automagically figures out the image's type (and size) based upon the file header. It doesn't even rely upon the .jpg or .gif ending, which would also be a bad idea.
