GrahamB2014: Firstly I am trying to import graphics(pictures of golf trophies) onto players walls for example when they achieve a hole in one. I have copied graphics to MY PICTURES on my PC [...]
You're correct, CE: The pic has to be online to be used here. There are some hosting sites, mine is postimg.org. Copy the URL from the "direct link" option, paste it into the "Insert Media" menu (green movie icon above the edit field) and limit the width to 450 for forum posts. You may also follow the "how to post a scorecard" advice on top of the "Help" forum.
A random snapshot of mine from NOLA, 250 wide:
To link to a post, you must first create&save the post, then grab the URL to your copy buffer, next highlight a text where you want to put it so that you can use the "Insert Link" icon in the posting menu. Use the option "Target: New window" preferably.
This is a link to CE's post.
