When I watermark, this program helps me out immensely. It’s called Pictul Watermarker and it ROCKS!! You just load in your logo and place it where you want it to go then run your photos through it! It’s that simple!! You can watermark 1 or even 101 all in a super fast click of a button. This has saved my oodles of time and I definitely recommend it. At only $35 it’s a steal. Check it out and you can even try it for free before buying!! Here’s an image I just edited using Pictul! Rockin’!!!!!
