// @name          Gallery Viewer for Broadband
// @namespace     http://joemck.cjb.net/
// @description	Loads full-size pic instead of reduced one in image/discussion page in some galleries.
// @include       *displayimage*
// @include       *album*

// Fixes an "feature"/annoyance in Coppermine and other photo gallery systems.  In such systems, you
// click on a thumbnail in a list of images to bring up the image page.  This page contains a reduced-
// size version of the picture.  You then have to click the picture to bring up the full-size version.
// This is a very nice feature for dialup users, but it's just plain annoying and adds an extra step
// for broadband users.  This userscript replaces the reduced version with the full one.
//   NOTE: If height and width params are set (like in some Coppermine setups), this script will still
// replace the image with the full-size version, but your browser will resize it.  Right-clicking and
// saving the pic will save the FULL size version, not the browser-reduced one you see.
// (If anybody knows how to remove height/width params in JS without setting them to 0, tell me.)
