>>>Eddie, I can't say the precise reason, but was the uploaded file in Adobe RGB or sRGB? I've seen similar problems when websites have applied compression algorithms when converting from Adobe to sRGB, although I don't think that can be the reason here. However, browsers aren't very good at displaying Adobe RGB. Try using the Save for Web function if you use Photoshop.<<<
The file is sRGB and I did use the save for web function in PS5. However, I did just notice that if you click on my photo, it opens a new larger window and there the image is displayed as it should be! That is a feature of this forum software I did not know about.
I wasn't sure on how big to make the photo - some people are likely still using smaller monitors and would have to scroll to see the entire photo, which can be irritating for some.
I just got the 7D and that was my first series of railroad photos I took with it. The camera and lens are really nice and the more I use it the more I wonder if I'll even finish the roll of film that is in my A-1
