You need to get a program that can open the screenshot so you can view it and save it.... Such as Infaview,which has free versions that open the screeny.
you might want to download IrfanView here: www.irfanview.com
This is an image editing program that allows you to convert the TGA file that trainz produces with the screen shots, inot any file type you wish to have. The most common one is .JPG.
Then, if your looking for a site to hsot your photos, try here: www.photobucket.com
Its free and easy to use.
Cheers, and good luck.

.Jpg files are the standard image files of today. You dont need a Jpg converter. Anyway, Irfanview converts any image, or what ever the item happens to be he wants converted into any image file type.
