I’m not sure how to add the Kutshort image to my profile
Alright.
INSTRUCTIONS FOR ADDING YOUR IMAGE TO YOUR PROFILE.
If I posted something you're using (or if down the road someone attaches their own character image on a post somewhere), easiest way is to just right click and copy image link. If you're on mobile, generally press-and-hold on the image gives the same option to copy the URL.

You'll copy the full URL like 'https://gwforums.com/attachments/1000003787-png.5092/'.
Go to your profile and click under Account Details.

Scroll to the Character Image field and paste the URL in there, then delete everything except the chunk as shown in the description. So of that URL of 'https://gwforums.com/attachments/1000003787-png.5092/' you want to just keep '1000003787-png.5092'.

Save your changes, and the attached image should show under your "more" information.
Character Sheet is the same, except you're just taking the number from the end of the 'https://www.dndbeyond.com/characters/115155185' link and entering that into the custom field.
