Clicking on a thumbnail photo will cause it to enlarge.  Under the enlarged photo is a link "original file" which will open a much larger version of the photo.

On the trip home from Cardston last weekend the sky was afire with thunderstoms.  I took several photos but somehow the CF card bacame corrupted so I couldn't download the photos.  I become obsessive about this sort of thing and determined to find a way to recover the images.  Google turned up this site: http://www.cgsecurity.org/wiki/PhotoRec and with a little luck the photos were safely transferred to my hard drive.
