I suppose you can insert regular IMG BB tag into signature and place the image on some photo site like Imgur?
Greetings thebert, You need to head to the Signature editing section of your Profile, then click the Icon. A box will appear allowing you to insert a image, using the URL of the image. That can be found by right clicking any image and selecting the 'Copy Image URL' function. Hope that helps you out! SkyblockGuru
Have you tried placing the picture as your signature? Ive found screen capture program links to not work well with signatures so I would try uploading the image you want to imgur then doing what skyblock guru suggests. I use tumblr and post images privately myself.
