Hi Tim,
We all have to start at the beginning some time.
When you say you've got your screen shots into your gallery, I assume you mean a web gallery like Flicker, Photobucket or similar. Hopefully you don't mean a gallery on your own computer. To post a photo in the Trainz Forums, you
must have the photos stored on a remote web site and most of the girls and guys choose one of the public sites mentioned above.
Okay, if you do have your photos in a public web gallery then all is okay. When you wish to display a picture on the forum, you simply add an address (URL) to the post telling the forum server where to locate the photo.
Provided your web browser is set up okay, it will show you the exact address (URL) of a photo when you visit your photo gallery to look at it.
Have a look at the top of the screen now. You will see a field with this address:
http://forums.auran.com/trainz/showthread.php?p=395249#post395249
This is the URL of this forum thread.
When you go to your photo gallery and display the photo you wish to show us, copy the address that appears in the browser address field. To copy the address, highlight it the same way you highlight stuff with your word processor. Place the cursor at the right of the address, Press the left mouse button and keep it pressed. Drag the mouse (cursor) to the left of the field and the address will turn blue. Release the mouse button. Type Ctrl C (keep the Ctrl key pressed while you type C). This is the keyboard shortcut for copy.
Now create a reply in the forum thread. Click the Insert Image icon and where you see
http://, delete that and type Ctrl V (that's the shortcut for paste). The URL for the photo should now appear in the field. Click okay and submit your reply. Your new post together with the photo should now appear in the thread.
Good luck.
John
