Update: I just recevied word back from Colin that the revised WordPress template is okay. That’s nice. Now what to do about those pesky ‘Snaps’, eh?
When I first previewed this template, the 750 pixel wide images were getting cut off by the sidebars. Then I loaded this 650 pixel wide image, which works, but so does the earlier 750 pixel image, which are not getting cut off any longer. So back to the larger 750 pixel wide images, which look nice.
All right, now back to our regular programing!
Best regards, Doug
Oi! After editing the post above, I realized that I did not provide the name for this image, which is Arizona Monsoon and it will be one of the 12 images in my Editioned folio Foundations.
Singular Images 
Aha – this one now works properly on both Firefox & IE. Nice thing, too, is that it resizs for my large widescreen at home and for the teeny tiny (19″) here at work.
