Make sure that you are allowing all images to load and that images from specific sites are not being blocked:
* In Firefox, look under "Tools -> Options -> Content" and
Make sure that "Load images automatically" is checked.
Open [Exceptions] and remove any sites being blocked.
Use about:config to make sure that the preference permissions.default.image is set to "1", the default value (right-click and select "Reset" if any other value is shown). [2]
* In Mozilla Suite/SeaMonkey, look under "Edit -> Preferences -> Privacy & Security -> Images" and
Make sure that "Accept all images" is selected
Open [Manage Image Permissions] and remove any site listed with the status, "site cannot load images".
Other reasons that images may not load:
* If images are blocked on site, click on the location bar's favicon for "More Information" and check the Media tab there for "Block images for ...". (If it is checkmarked, you probably did not open the Exceptions button above).
* Even if you can see the site and some images, third party images may still be blocked from other sites by Extensions such as "Adblock Plus" or with a hosts file.
* The site hosting the images may be down or experiencing difficulties, try loading the site from another computer or browser to see if this is the case.
* A router or security software is blocking what appears to be an excessively large number of connections (interpreting it as a "SYN flood"). This can be caused by changing network settings in Firefox, or by inappropriate settings in the router or security software.[3]
* Images from a site can be blocked from a context menu (right-clicking, in Windows). A site could be blocked accidentally by right-clicking on an image.
* If images such as google maps don't load (or won't zoom in and out): In Mozilla Suite/SeaMonkey, go to your advanced JavaScript settings and make sure "Change Images" is enabled. This option was removed in Firefox 1.5 [4] so you'll need to type about:config in the address bar and check the list to verify that the related preference dom.disable_image_src_set is set to "false". If it isn't, context-click (right-click) the preference name and select "reset", or double-click to toggle.
* Some image references contain backslashes (e.g. something.com\blah.jpg), which cause the images to be loaded in Internet Explorer but not other browsers. If you see the image's URL contains a backslash, contact the webmaster about the issue. The Slashy extension will let you work around this problem.
* Some sites will block the request if no referring URL is sent. Use about:config to make sure that the preference network.http.sendRefererHeader is set to "2" (default) and reset, if necessary. Also make sure that all proxies, firewalls, and other security software allow the referrer to be sent.
* As a security precaution, references to images on your local computer from a remote web site are disabled. If you encounter this restriction and you understand the security implications, you can disable this security measure.
* Problematic extensions can cause images not to load. If you have one of these extensions, you can disable it in Firefox via "Tools -> Add-ons -> Extensions":
o Among other issues, the Skype extension for Firefox (installed with Skype) can prevent images from loading and causes the error, The image cannot be displayed because it contains errors. [5] [6] [7]
The "RealPlayer Browser Record Plugin" extension (included as an option when installing RealPlayer) can cause images on a web page to no longer display if you reload the page [8] [9]
