Followup: <i>Hmmm, I have no idea how this happened, but in Firefox it appears that somehow a setting was changed to block images from my own domain. I right clicked where the banner image should have been and noticed the checkmark beside the option. Too strange.</i>
A strange day here. Yesterday everything was tickety-boo and worked fine. The only unusual activity was an install of MS Office on my Powerbook, and removal of NeoOffice.
This morning half of the images on the blog (including the banner) don't display in Firefox, although some do.
As well, when I went to make a post, in both Firefox and Safari, the editing button bar that should be across the top of the text edit window has disappeared.
Everything looks fine on my PC.
I'm guessing that MS Office nuked some setting in Firefox, or maybe the java on the Mac? Any ideas?
