We have launched QuickPic, a single column wordpress theme, which is ideal for photoblogging. Powered by 3 columns in the footer, it has adequate space for photobloggers to showcase their content. Of course it can be used as a one-column clutter-free wordpress theme by all bloggers.
QuickPic is widget-ready, SEO-optimized, Ad-ready. The width is particularly set at 500px to easily fit in embedded images from Flickr.com. It is released under a GPL license, which means you can easily edit it, change colors as per your liking; and of course it is available for download free of cost.
Visit the QuickPic theme page for more information. Try the live demo and download QuickPic if you like it. This is our second wordpress theme after QuickPress, and I appreciate your feedback to help us improve the theme.
