I'm going to have a play with FastStone - as it has the watermark facility as well. Unfortunately my old version of photoshop has made this not as simple as I would like - and FastStone looks to be able to do it all a lot quicker. I'll report back ...
for a simple freebie ..easy thumbnails ..here [www.notetab.com]
cant remember if it does watermarks ..haven't used it in years ( I use photoshop )..but it is "easy" and fast ..and "free" ;-) ..the guy makes some very nice software in general ..free and paid ..
thanks for that Mike - however in the interim I downloaded the above - and it does everything I need really quickly and easily. I'd recommend to anyone who needs a fast bulk image editing tool. Does the watermark at the same time - as well as numerous other things if you want to tweak.
