You guys are really good at this! Thanks very much!
The variation in the display size is automated by Jalbum and seems to be related to whether the photograph is horizontal or vertical. Jalbum tries to fill the frame without causing scrolling. In addition, it also seems to adjust slightly in response to aspect ratio. Since many of my photographs are made on 6x7 chrome, the aspect ration is different from the normal 35mm/digital ratio.
The Alaska photos are mostly digital but most of the rest are originally film, usually Velvia. For the last several years, I have made a practice of having my film scanned when processed but for some of the older ones, I do not have really good scans. The one you mentioned is an older 35mm scan that is not very good. There is some damage to the chrome that should have met with PS. I'll get that fixed. Thanks.
The two Denali photos differ only in the position of the Dall sheep. I should choose one. The two from Kenai (639-640) are nearly identical, I will remove one. I'm still working through the Alaska shots (I just got back about a month ago). There are many more and I will be making some changes. I'm also going to organize them differently.
I have many more Oklahoma shots that I think are worthwhile and cover a variety of subjects. There will also be a new Arkansas gallery and more for the Colorado gallery.
The file numbers are only for precise identification.
I will see if I can get some navigation among the different galleries. I thought the browser back button would be enough but others have mentioned this as well.
I am especially appreciative of comments about the galleries because I want them to work well and I am learning a lot about what others expect and how it differs from my own expectations. Thanks.
