Maybe I'm not asking the question in the RIGHT way. My problem is with the editor itself, and how it handles BB Codes. So I'm going to try to restate my problem:
The editor has 2 modes:
"Rich Text" to display what the post will LOOK like.
"BB Code" to display the codes and text that create the post. If I WANT to see/edit the BB Codes, I can select BB Code mode.
In "Rich Text" mode, it's supposed to visibly display the text and the RESULTS of the BB Codes - and does so for font, color, indent, bold, etc. codes. So the effect is WYSIWYG for THOSE codes.
But "Rich Text" mode does NOT display the RESULTS of QUOTE or ATTACH codes - it displays the BB Codes themselves even though I'm NOT in BB Code mode.
SOME codes are WYSIWYG and other codes are not. So "Rich Text" mode is only sorta-kinda-almost WYSIWYG. It's obviously POSSIBLE to display the photos in the edit window - it DOES display them when creating a new post, but doesn't display them when editing an existing post.
If I want to see what the post will REALLY look like, the only way to actually SEE the post is to submit it. "Preview" doesn't even display it EXACTLY like it will appear when submitted. And then I have to edit..submit..edit..submit..edit..submit until it eventually looks right.
This makes creating and fine-tuning tutorials or demos that include illustrations MUCH more difficult than it needs to be.
