This is one of the best plugins I have come across for managing images. However I am having a few issues since upgrading to WP 3.5.1 - and I am using version 2.18 of Grand Flash Gallery
Issue 1 - the flash uploader is not working. When you select a single or a number of images for upload using the Flash uploader it just sits there looking at me.
Issue 2 - the music album does not play automatically on the sidebar even though its selected to do that. Hence I had to resort to another plugin for music on the sidebar.
Any help would be appreciated. Again this is a great plugin, that's why I bought some of the skins.
