Well, it didn't nearly take me as long as I thought. My design of my pictures page is complete. I'm really pleased with the layout, and it definitely encourages me to keep it updated more frequently. This week, I have uploaded 109 pictures, including two picture collections: Florida Trip 2006 and Roden Reunion 2006.
The pictures page now has three sections: a display of the latest 20 pictures added to the site, the most recent collection added along with an ability to select any other collection, and a calendar-like grid showing the number of pictures from each month and year available. These changes meant I had to update several other components, most notably the search page. I still have a few tweaks to make, but everything is functioning well.
