## Author Notes: 
##
## This is a simple MOD to resize the user's remote avatar if it is larger than the 
## maximum size set in the admin control panel. It does so through the size constraints
## in the HTML <img> tag.
##
## NOTE: It does not resize the actual image, just scales it in the HTML codes
