Can you attach a screenshot?

Use a compressed image type like PNG or JPG to save the screenshot.

Make sure that you allow pages to choose their colors and that you haven't enabled High Contrast in the Accessibility settings.

• Tools > Options > Content : Fonts & Colors > Colors : [X] "Allow pages to choose their own colors, instead of my selections above"

If images are missing then check that you aren't blocking images from some domains.

• Check the permissions for the domain in the current tab in "Tools > Page Info > Permissions"

• Check that images are enabled: Tools > Options > Content: [X] Load images automatically
• Check the exceptions in "Tools > Options > Content: Load Images > Exceptions"

• Check the "Tools > Page Info > Media" tab for blocked images (scroll through all the images with the cursor Down key).

If an image in the list is grayed and there is a check-mark in the box "Block Images from..." then remove that mark to unblock the images from that domain.

Make sure that you do not block third-party images, the permissions.default.image pref should be 1.

There are also extensions (Tools > Add-ons > Extensions) and security software (firewall, anti-virus) that can block images.

It would seem that the graphics names show with a box around them but no graphic...

It sounds that you see the alt text associated with the images and that the images are blocked.

Did you try the above posted steps about missing images and checked the image settings in Tools > Options > Content and the images in Tools > Page Info > Media to see if they show there ?
