Nice galleries, easy to use, not great for SEO / performance

This is a really nice gallery system, with nice galleries, especially given it’s free. There are a couple of enhancements that would make it much better (these are copied from Google Pagespeed test / GTMetrix)
– Eliminate render-blocking JavaScript and CSS in above-the-fold content. Basically move JS/CSS to the footer where possible.
– Images are resized in HTML or CSS, rather than serving thumbnails. This makes the pages much larger, and SEO tools don’t like it as much.
