Trouble with RSS feed

I am new to this and have a question. My site is: https://www.loseyourself.org
The window at the upper right is supposed to (I think) take Picasa images from a Picasa gallery I have set up. WP tells me to go to the RSS feed area and copy the information. I assume its the URL its after. I copy that and put it into the field, but the window is blank as you can see.

If anyone knows about such things, I would be very pleased to learn.

Thanks
