Hi Paul, 

The links have been broken for ages, and like you I assumed the image files
were missing. Not so. I noticed very recently that it's just that the image
references contain explicit IP address that are no longer valid, presumably
because the servers were moved without the HTML being updated to match. If you
right-click the "X" image and choose properties, you can see the URL contains
the bad IP address. Copy/paste that into another browser window and replace
the address with www.photodo.com and presto, you'll see the chart. For
example, the link for the Canon 50/1.4 USM:

http://193.14.88.41/pix/lens/mtf/CAEF5014.gif (broken)
http://www.photodo.com/pix/lens/mtf/CAEF5014.gif (works fine)

BTW, as you are probably aware, the lens pages take an age to load on most
browsers because of the broken reference. You don't actually have to wait for
the "X" placeholder to appear, you can just right-click the empty space after
the results summary. Doing a Select All makes it easier to see where the
placeholder is (generally just underneath the "D" of the Distortion result in
the summary).

I was checking for some lens test information and noticed that I'm no longer
able to get the http://www.photodo.com/nav/prodindex.html MTF curves.  Any
idea as to what has happened to them or if they are available elsewhere?
Those and the (other?) Swedish tests are about the most reliable I've even
found, even if they seem to have stopped updating them long ago.
