This is how I do it:
1. Search for "Snipping Tool" in your search bar and open it.
2. Go to your character UCP and click
New on snipping tool.
3. Drag with your cursor so it displays your level, character name and all the necessary info.
4. Save the Capture somewhere near, like Desktop.
5. Open
IMGUR
6. Drag the Capture in IMGUR and wait for it to upload
7. Once it uploads, right click on picture and click Copy image address
8. Go to forums and paste the image address where needed and place between it. Example
