There is a hook called "wp_handle_upload" that is called right after an upload for (at least some?) file uploads. It gets two parameters:
'file' => $filepath,
'url' => $fileurl,
'type', => $mimetype
There are several functions for addressing image size in WordPress and PHP but image_make_intermediate_size($filepath,$width,$height) might be what you need. First find out of the file is too big using getimagesize():
list($width, $height, $type, $attr) = getimagesize( $filepath );
If so resize it to your max size (this example assumes your max would be 640x480):
Hope this helps.
