[UPHPU] File upload validation

[Trevyn Meyer]

Have you ever written a file upload validation?  What methods seem to 
work for you?  I have tried PHP mime type, but ran into problems where 
the OS thinks its one things and php thinks its another.  I have some 
jepgs uploaded that recive no mime type.  I have also tried the linux 
file command and it works ok, but with no great success.

My main application uses latex, and latex only accpets system recognized 
pngs and jpegs.  Im thinking about using image magic to press everything 
down to a jpeg, so I can then process non MIME typed images, and gifs 
and such.

Have any of you written a better upload validator?  Also, let me know if 
any of you would like some work.  Illpost on the job board. 

I want to combine
http://uber-uploader.sourceforge.net/
with iamge magic for
mightyauthors.com [Deisgner is meeting with them.. so dont judge by the 
cover please :)]

Mighty Authors is a Latex template system, that allows people to fill in 
the gaps and write books and projects using latex2pdf templates
