Anyone had experience with the woo-commerce watermark plugin ? From my own mucking around it seems a great concept, but in practice hard to deal with. Works on occasion, though in the most not.
The only thing I've ever used is Imagemagick running server side or Irfanview for batch processing prior to uploading
