LeftofCenterus saidDoes that work for photos I post on my personal profile?
Yes, as you see above from my own RJ profile. Go to your profile and enlarge a pic there. Then right click on it. Depending on your browser, select VIEW SOURCE or INSPECT ELEMENT or similar.
That will show you the HTML code, many lines long. Look for a line element that begins with "http" and ends with ".jpg"
This should be your profile image. Copy that, then paste it to your thread post. Highlight it and click on "img" above the text input box. Click on PREVIEW MESSAGE to verify you did it correctly, then click SUBMIT.
