Hi - firstly this plugin is brilliant and I've always found it works well so far. However I've just moved my blog to a new host and its screwed up the galleries aspect of the blog. The files shown in the galleries have become the full sized versions not the smaller ones although the smaller ones are still in the same directory as the full sized files. Creating a new blog with a gallery with new uploads works fine.
Happy to supply any further info but any pointers as to where I can look to solve this issue would be great. Thanks
