I love this plugin, thank you for creating it!
One issue I ran into, I hope you might be able to lend assistance. I have created 5 galleries with the intention to have 1 different gallery on each page (totaling 5 pages).
On each page, I have this posted: [print_gllr id=my_gallery_id] with the unique gallery ID (I assume this ID is the gallery=my-gallery etc... being my-gallery in this instance) on the page. Each page has a unique gallery id on it, however, the same gallery displays on ALL pages regardless of ID and it happens to be the last gallery created!
