Hi there. I think you should use the Feed Manager module for this. Using your posted RSS feed I was able to set up a feed manager instance with your photos on the demo site (although it might not be there by the time you see this), and it works fine for me in Firefox 4. Basically I just dropped Feed Manager on the page, added your RSS link to the feeds, and changed one security setting: in order to include images, you need to check the box for "Allow External Images". This is off by default for security purposes.
