I have found two images that do not turn up when searched...
HDR does not bring up Steeples (and Steep doesn't do the job either) by phasmid while he has HDRland in his description. HDRla won't be found either though HDRland will!
Simply The Best does not bring up Simply The Best (and Simply doesn't do the job either) by ls123 (Lin)
A search for HDR brings up all (I imagine) images with (HDR) in the title.
I hope the solution to this problem can be found. :o)
