but the site shows up fine in Safari, Internet Explorer and Chrome.
If I use "view page source" in Firefox and click directly on the image links in the code it sees, then it shows the image. But when I click back, it doesn't display that image on the page.
I found the problem. I went to "Tools > Page Info > Media" and the box for "block images from this site" was checked ... why, I don't know.
If anyone has an answer for that, I'd love to hear it! Why would Firefox suddenly decide to start blocking images from a site I've been working on all day?
