## MOD Title: Limit Image Width MOD
## MOD Author: Vic D'Elfant < vic@pythago.nl > (Vic D'Elfant) http://www.pythago.nl/
## MOD Description: This MOD will scale each image in a post so it does not exceed
## the maximum image width set by you. Smaller images will retain their
## original size.
## When clicking such a scaled down image it will open at its original
## size in a separate popup window.
## The image dimensions will be cached in order to avoid unnecessary
## delays when loading a page and checking the image dimensions
##
## MOD Version: 1.1.1
##
## Installation Level: Easy
##
## Installation Time: ~5 Minutes
##
## Files To Edit: includes/bbcode.php
## templates/subSilver/overall_header.tpl
## languages/lang_english/lang_main.php
## languages/lang_english/lang_admin.php
##
## Included Files: admin_liw.php
## liw_body.tpl

## Author Notes:
##
## * Note that since this MOD checks the image width of each posted image
## the loading process of a page containing [img] tags could be slowed
## down when _caching_ an image
