First off, great plugin. I've found it works great in most browsers, however I found a tiny hiccup:
I could not get the modal window images to work in IE9, 8, 7, and 9's compatibility mode. It either displays as a red X or doesn't display anything at all. Have you encountered this before? It's working fine in all other browsers. This is with using the gallery shortcode with choosing each photo's ID to display in the gallery.
Also, I noticed in a forum post created about 6 months ago that you have included the ability to add a filter so this plugin could point to a different CSS file. I made the mistake of updating the plugins css files, and shortly thereafter everything was overwritten, causing me to explore other options.
- If you would, please tell me where I may put this filter so I can re-direct the css to my own. Do I put it in my theme's functions.php? Or do I put it in the plugin's sm-gallery.php itself?
