I've only been on this website for a few weeks, and i really do think it's great. Although, one thing that could do with being changed is the sequence which we view our images. i.e., when anyone views our profile page, containing our individual thumbnail images, you need to click on any thumbnail to view that particular image, in full, which is fine. However, you then have to click back into the thumbnail gallery, in order to click the next thumbnail, to view that image. If the website is ever redesigned slightly, it would be handy if we could click a little forwards/backwards button beneath, or to the side, of the full-size image and view the next one, without having to go back into the thumbnail page. [Although, that option should still exist too]. I tend to view only a small selection of their full-size images, because it's too time consuming to keep going back into the thumbnail page, which is a pity when you come across members who have amazing photo, after amazing photo, and you want to look through them all!
Otherwise, i have to point out that i really do love this site. It's great to view other gallery members amazing images and receive valued feedback on my own.
