Subject: * Add preview parameter to preprocesser calls, use this rather than
 the   previous ugly hack used to avoid writing rss feeds in previews. * Fix
 the img plugin to avoid overwriting images in previews. Instead it   does all
 the work to make sure the resizing works, and dummys up a resized   image
 using width and height attributes. * Also fixes img preview display, the
 links were wrong in preview before.
