I've submitted two pictures to Railpictures.com only to have them rejected. The second one was rejected on this account:
"Poor lighting (Cloudy): Common angle cloudy day shots of common/standard power are generally not accepted." Alrighty then. I give up trying to get my pictures posted on their site. Why do I need to post them on their site anyway? I have my own site and I am the editor. If someone is looking for a locomotive, they usually use Google to find pictures or location information.
