Hey RLShare nice mod... Installed exactly how you explained and works straight away... However I see you are re-making the mod... PLEASE oh please add the relative size watermark that has been suggested numerous times...
Suggestion For Re-Haul:
Allow of placing wm on images already created (done with the update counters...photopost have it....)
Is it possible to make the plugin somehow put the watermark on AFTER the image gets re-sized? As it is now it seems the WM gets placed befor the image gets re-sized...
Example of why (my watermark image is 150X30... on a 600X450 image that was originally taken off 5mp phone camera):
