This site is a spin-off from Bulk Resize Photos (
https://bulkresizephotos.com) which previously had a very limited watermarking capability. I surveyed users about why they wanted to watermark their photos and what types of watermarks they would like to use, and Batch Watermark is the initial result of what I learned. It certainly still has some rough edges and is still in the "if you aren't embarrassed, you launched too late" phase.
