I hope this doesn't seem to be too critical sounding, because overall I love the work that's been done so far.
I'm enjoy building a gallery and uploading images to it. However, I see one really confusing thing about viewing these galleries. Whenever I test something for someone, I like to pretend that my knowledge level of web pages is very limited. So, when trying to view the picture galleries in this limited user mindframe, I find that some of the styles are extremely user-UNfriendly at this point in development. It is not very clear where a user should click to see a gallery from the User's main picture index (the top level). The best of these in this regard is the "Cornered" style, which actually says "Choose a gallery." I feel that all of the styles should make it so blatantly obvious for the viewer that this is a gallery and you click here to view it.
Another general comment I have about the styles is the navigation through the galleries. I know the purpose of styles is to give everyone a little something different to choose from and meet their own personal style, but perhaps some things should be basic to all styles, especially when it comes to user-friendliness and ease of navigation. For example, in "simple format," it seems very obvious to me what I need to do to navigate to the next photo or previous photo within the gallery. There are very big buttons and easy to notice. I do think, however, either some text or alternate text on the buttons would make it more more obvious to the user what these navigation buttons do (example: next photo, up to gallery level, etc). There's also a little snapshot of the image which would be next and which is the previous. It's pretty easy to navigate through.
However, when I switch to the "Cornered" style, for example, I found it difficult to find the navigation buttons in the first place. They are these tiny little arrows, really tightly squeezed together, and seem a little more confusing either because of their size or their proximity to one another, or both. I do like that this style does have alternate text over the buttons. However, I feel it would be helpful if the buttons were bigger and were more obvious--easy to see.
I guess my overall suggestion regarding styles is that the navigation into and within galleries could be made more obvious to accommodate all "Internet User levels."
