Buttons
The button should be the PrtScn one, that works in all versions of Trainz as far as I know.
Once you have them you will need to change their format from a tga file to a jpg. Do this with Paintshop or PainstShopPro or even Paint, I think that does it now.
I usually resize each to 800x600 at the same time.
All screenies are stored in the Trainz directory under the folder Screenshots. Just double-clicking on a tga file should cause it to open in whatever graphics program you use.
They will save to the Screenshots folder. So for convenience I make another folder called something like Auran/pics on my C:/ drive and transfer the ones I am going to upload there. You can upload straight from the Screenshots folder but when you get a lot in there it gets complicated....
Then you will need a free account at an image hosting utility like photobucket or imageshack - or both if you like.
Once you are signed in and have your account you can upload the images you have worked on to there.
I find photobucket is slightly easier because the bottom line of the saved file names (you'll see them under each image...) can be higlit, copied and then just pasted into the thread you have chosen and your particular post. A Return will put a space between pictures.
It is nice, polite and usual to thank whichever hosting service you have used for doing it for you at the bottom of the post.
