Single post in A Somewhat Extensive Guide to BBCodes

I read through the entire thread, if I somehow missed this, I apologize for the repeat. Is there a way to show a screenshot without actually to uploading it onto a site? I noticed the image BBCode is focused on URL. This will be very useful to me when I'm making reports and a screenshot is needed if I don't need to upload the screenshot. I don't use sites like TinyPic, and I don't want to upload it on other sites such as FurAffinity.(It's like deviantArt except for furries if anyone doesn't know what this site is) If you can do this, but does not fit in the BBCodes, I do apologize for asking this in the wrong thread.
