You can "Batch Watermark" a bunch of images with Photoshop's Batch feature. There are several ways to do this. One way is to open all the images you want to watermark in Photoshop and then run the Batch command. This can use up a lot of memory though, so if your system doesn't have much memory, then you should limit the images opened to a few at a time. If you do have a decent amount of memory you can open a lot more. Here we have some images opened, all the same size to work with our watermark action, and ready to go.



Once you have your images to be watermarked opened, select the "Batch" feature by going to the "File" menu, scroll down to "Automate" and then slide over and select "Batch."



You will be presented with this dialog box. In the "Set" field, select the "Action Set" where your watermark action is. In the "Action" field, select your watermark action. In the "Source" field, select "Opened Files." In the "Destination" field, select "None." In the "Errors" field, select "Stop for Errors." You could change source to "Folder" and run the watermark on a bunch of images in a folder, but sometimes this does not work right or smoothly, so I'm showing you how to do it on opened images. Click "OK" to run the action on all opened files.



Here's the effect of our batch watermarking. I'm happy with it ;)



I hope you found this tutorial useful in making actions to watermark your images. Remember to make a separate action for each standard size you want to watermark. In the process, I hope you learned something about the power of actions and how to create them. They are pretty simple, just press record and do something and it play it back!
