Yeah, thanks! I went ahead a posted. Not sure if it is too hard. The actress above was more famous for her singing than her acting.
That used to happen to me all the time. Generally whatever pic you choose has to be first saved on your computer: either desktop or downloads, or wherever you store pics. Then you can use the "Manage Attachments" feature, and capture and insert the image into your post.
Give it a whirl.
