www.photobucket.com is better. All you need to do is covert the image to a JPG file, then upload to photobucket. but you need CovertImage to convert the images to a JPG file instead of a TGA file
I use Photofiltre, myself, but either one will do what you need.
And they're both free. What a deal!
Don't worry about another Tehachapi. There's always room for a different interpretation.
If I remember the route at TRP was made during a early version of Trainz
I think UTC and a lot of content made from the first version of Trainz did not show up in Trainz 2004 and 2006. I would welcome a new version of this route.
