## Author Notes:
## This MOD will automatically resize the uploaded avatar to the
## Maximum Avatar Dimensions set in General Configuration. For example,
## if you upload a 400 x 300 avatar and the admin set avatar size to
## 100 x 100, this MOD will resize the avatar proportionally to 100 x 75. 
## This MOD handles GIF, PNG and JPEG images. This MOD requires the
## GD Library version 2.0.28 or higher. I deleted some instructions
## on the profile page, so if you have a multilingual board you must
## apply the change to lang_main.php of each language. After applying
## this MOD, Maximum Avatar File Size in General Configuration will
## apply to the original avatar before it is resized, so you might
## as well set it to something high like 2048000 (2000 KB).
