This seems like exactly the plugin I'm looking for, and am hoping you still offer support for it.
I have a WordPress installation in a subdirectory on my site:
I've set the .htaccess file to redirect calls to the root to the subdir (when you go to the URL, you don't see the subdir). This seems to only be the case on the public side, not the admin side.
It seems that Media Mentions is looking for an installation in the root and therefore isn't finding the files it needs to operate. Specifically, it can't seem to find any image files (even the Amazon logo and PayPal donate images). It doesn't offer a list of logo selections, nor generate a collage image.
For testing I've hardcoded my subdirectory in media_mentions.php and have gotten close, but I'm at the limit of my knowledge and was hoping you could offer some help.
