Any possibility to disable highlighting?
I then tried wrapping the link text as per the pinned topic Inlined Images with , which did result in inline pictures, but again the same VERY small ones. So it sounds like what you guys are saying is the only option for the text box jpgs is as attachments below. That's fine, I'll just reference them in the body and name the files appropriately as the names are visible on the links.
Inlining attachments works but is rather cumbersome. It is described in Korth reply in Attachments topic:
[attach type=image]n[/attach]
...
Where n is the attachment number. To find the attachment number, add the files to and post the message. Open the message and view the URL of each attachment (this can usually be achieved by hovering mouse pointer). Look for attach=nnnn in the URL (nnnn is the attachment number). Edit your message to add the attachment number(s) to the tag(s) and save the changes.
