You appear to be mostly correct in your assumptions about the modification of these photo URLs. I would STRONGLY discourage modifying those URLs directly, and instead encourage you to use the query params provided for the image sizes:
http://code.google.com/apis/picasaweb/docs/2.0/reference.html#Parameters The brief story is that setting imgmax=1600 will return the large images that used to be returned in the media:content element. You can also set a comma-separated list of thumbsize= params, such as thumbsize=144,1024 to get a set of thumbnails sized as needed. There is a known issue on exists code that returns the wrong size in the media:content element when there is no imgmax size set. The image being returned from that URL is defaulted to 512, but the width/height are not right at this time. I'm sorry for that bug, but I have a fix and should have it out tonight or tomorrow, I hope. I hope this helps.
