I am now thoroughly confused. I have upload new site with ss 2.4 and have DOM and Image gallery. I have an image gallery page top level and all albums work fine. As soon as I go down a level and setup a image gallery page it throws up an error when I click on an album. Works Top level works, not sub level. Wacky any ideas.

Line 194 in /www/sw1b/image_gallery/code/ImageGalleryPage.php
Seems like a possibility as I have been working on existing sites with 2.3 and new sites with 2.4 so could be mixed up somewhere. Can I just copy all files/folders except the templates or have the template got new elements.
You should never have to modify any of the templates, code, or CSS in a module. Silverstripe gives you a full-featured theming framework.. use it!!
Any template you place in your theme dir will override its counterpart in a module. Same with CSS.
If you add /your_theme/templates/Layout/ImageGallery_album.ss to your site, SSViewer will look there first before falling back on the default templates for ImageGallery. Likewise, /your_theme/css/ImageGallery.css will override the core CSS.
Modules should remain insular so that you don't have to pull your hair out when an upgrade comes out!
