I did not create this mod, I simply reworked some coding from a punbb 1.2 mod, all credit goes to the original author "thame^" who's mod for 1.2 can be found here
##
## Mod title: Automatically resize uploaded avatars
##
## Mod version: 1.0
## Works on PunBB: 1.3.*
## Release date: 2009-12-11
## Original Author: thame^
## Update Author: Source Code
##
## Description: PunBB's default behaviour is to reject any uploaded avatar
## image whose dimensions exceed those set in the options.
## Using this mod, PunBB will attempt to automatically resize
## those images to the maximum allowed dimensions, maintaining
## their aspect ratio. If the file size of the _resized image_
## is larger than allowed by the options, the upload will still
## be rejected.
##
## Affected files: profile.
##
## Affects DB: No
##
## Notes: This mod requires the GD image library, including support
## for at least JPEG (GIF and PNG are also recommended). If
## your copy of PHP is compiled without GD support (or lacks
## support for the uploaded image type), the mod will silently
## revert to the default PunBB behaviour. Visit
## http://php.net/gd for more information about the GD image
## library.

## own risk. Backup your forum database and any and all
## applicable files before proceeding.
