The image cannot be displayed because it contains errors

If you receive the message that an image cannot be displayed because it contains errors, see The image cannot be displayed because it contains errors article.


Security software

Some Internet security software (including antivirus and anti-spyware programs, firewalls, privacy programs, and others) may identify and block certain images as web bugs or may prevent images from animating. Check the settings for your Internet security program to make sure it allows images to load.

Images load the first time but not later

The RealPlayer Browser Record Plugin extension (installed with RealPlayer) can cause Firefox to show images correctly upon the first visit to a website, but not on subsequent visits or refreshes. Disabling this extension will fix the problem.

  1. Open the RealPlayer program.
  2. Go to the Tools menu and click on Preferences.
  3. Go to the Download & Recording section and uncheck the option Enable Web Download & Recording for these installed browsers:.

  4. Click OK.

Or see the Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems article for instructions on how to disable or uninstall extensions in Firefox.


Images load but look wrong

If images on websites load, but don't look right or don't look the way they do in other browsers:

  • If the colors in the image look incorrect, try the solutions in the Website colors are wrong article.
  • If you are using any sort of web accelerator software, disable it and see if images load properly. For more information, see the documentation that came with the software.
  • If the image area shows text or some form of gibberish, see the MozillaZine Knowledge Base article Page displays as gibberish.


Other reasons why images may not load

  • The site that displays the images may be down or experiencing difficulties. To verify, try loading the site from a different computer or browser.
  • Some pathnames to images contain backslashes (e.g. example.com\MyImage.jpg). In browsers other than Internet Explorer, these pathnames do not load. If you see that the image's URL contains a backslash, contact the site's webmaster about the issue.


Images still do not load correctly
