I'm new to NextGen gallery and still a bit new to WP. I'm creating this rather crazy custom site for a photographer. On her gallery pages she would like thumbnails in 2 different sizes. I have been able to accomplish this with the NextGen Gallery plug-in, but in trying to get all the thumbnails to fall into their correct places I am having to create a custom CSS and position them using their IDs. This is fine until she goes to change the images and they will have all new ID #s and the layout will break.
I'm wondering if there is a way to a custom class to the some of the thumbnails so that she won't have to edit the CSS file every time she wants to change the images.
