[Plugin: DynPicWaterMark] Watermark images held in galleries

I love that this plugin allows you to use an image rather than just text. I have gotten it to work on my normal posts and pages however my website is a photography website that utilizes galleries. Anyone know how I can get it to work within the galleries (almost all my pictures are held in galleries). Currently only the posts under the blog have the watermark.

Also, when I click on the picture and it opens it in a lightbox the watermark is no longer there. Anyone have any ideas. Here is my website:
