I realized today that I never posted about experimenting with jQuery Mobile last semester. The jQuery Mobile framework made it pretty effortless to search and display photos that I uploaded to my server and tagged.
The appropriately named, Photo Feed web app can be found here. Try it out in any mobile browser. You can test uploading pictures by emailing them as an attachment to feedmephotos [at] gmail.com. The subject of the email will be the title of the photo and multiple tags can be added to the body of the email, separated by a space.
