Upload error - image size problem?

[mattpage]

Hello. I am trying to upload images that are sized 1632x1224. As this is the size that comes out from my camera phone it would be much easier to be able to upload these straight rather than re-sizing them.
But everytime I try I get an Error.
I find the file, click 'continue' then the next page I click 'continue' and it brings up a white page 'Internal Server Error'

I think its becasue the files are too big, as when I resize them to 800x600 they do on fine.

In the config my settings are:
JPEG quality - 90
max dimention of a thumbnail - 100
use dimention - max aspect
create intermediate - yes
max width/height of intermediate - 500
max size for upload - 2000kb
max width height for videos/pictures - 4000pixels
auto resize - yes everyone

Is there anything there stopping me from uploading the images? Or perhaps a different part of the config?
