I have been working with IPB to fix the following issues which have recently come to light:

Signatures not aligning properly within posts with images. I have rebuilt the skin and all is now fixed.

Blog images not showing in blog posts. This is still work in progress.

The following error was appearing if an URL was posted in a post or message relating to the gallery:
Fatal error: Call to undefined method skin_gallery_global_23::bbCode() in /home/macmedal/public_html/admin/applications_addon/ips/gallery/extensions/bbcode/gallery.php on line 298
This has now also fixed.

Any further ongoing issues please report them in the software errors and troubleshooting forum.
