Ability to watermark multiple photos at the same time would be a lifesaver for photographers. Check out SmugMug’s go to on this. Please incorporate same thing.
My agency does a lot of photography. It's essential that we're able to batch watermark multiple files! it could be like a "watermark this folder's contents" option.
HUGE upvote here. I can't believe Dropbox still doesn't allow multiple files to be watermarked in one step. Incredibly behind the times. This is an essential feature.
