The editable_image() template tag is very cool, but I can't get the "Change Image" button to show up reliably in the media uploader. In FireFox I it appears in the "Media Library" tab but not the "From Computer" tab. In IE8, I get "Permission Denied" errors in "Media Library".
I put some effort into solving this, but failed so far. IE8 especially stymies me.
I believe the relevant code is in
editor/editor.dev.js:307 replace_button(). I found that since the media uploader is loaded for post ID 0, there is no submit button to be replaced. I tried appending it instead, but the livequery didn't seem to fire reliably.
This would be great to get working, but I'm unsure what to try next.
