Well.... Besides the normal... What browser/version. I noticed CSS warnings with my old version of Firefox, but no errors, or anything with JavaScript.
Do you have any extension pop-up blockers? Or using the browser built-in that could be blocking it?
If that doesn't work then you can switch to doing the raw HTML with the HTML button. An image tag is like:
Code: |
<img href="http://someplace.com/path/to/img.jpg" title="Image Title" alt="Image Text"></img>
|
href == URL of image
title == Text that shows up when hovering over it
alt == Alternate text for Screen Readers
Umm... err... yeah.
Don't know if the pasting of the Image URL works as Kagome Yuki Niwa mentioned... haven't ever attempted that, but the editor may be smart enough to do that.
