Are you trying to embed those images on a website? There is a maximum supported image size for that and it is 800. Here's an excerpt from the API online reference guide: (http://code.google.com/apis/picasaweb/reference.html#Parameters)
"The following values are valid for the thumbsize and imgmax query parameters and are embeddable on a webpage. These images are available as only uncropped(u) sizes by appending u to the size or just passing the size value without appending anything. 200, 288, 320, 400, 512, 576, 640, 720, 800 The following values are valid for the thumbsize and imgmax query parameters and are not embeddable on a webpage. These image sizes are only available in uncropped format and are accessed using only the size (no u is appended to the size). 912, 1024, 1152, 1280, 1440, 1600" Try requesting with "imgmax=800" and see if that solves the problem. This query parameter will automatically add a 's800' path element into each image URL (just before the image name).
