After Sucamarto posted on Turbine's forums on the lack of a portal.dat image for patch pages I dug up a collation utility I made over a year ago but never finished up and completed it. I've started filling in old patch pages, though I've had trouble extracting a small number of low color icons that use a different format. Once I get it sorted I'll update any existing images and finish the rest up (I got up to around ToD 2005 so far).
The false backcolor isn't true black (it's off by a single tick, so you can floodfill them to remove it. But they also have the hex ids for identification if you need to pull out an original.
