Every website I go to, has blurry pictures on it. I
Since it's only websites where images look pixelated, try some of these suggestions, especially the first:
Clear your browser cache, close it, open it, and then refresh your browser.
If you're using Internet Explorer, check the Advanced settings in the Internet Options. Under Multimedia, select Smart Image Dithering to see if it helps. If you're using a different browser, check for similar image quality settings.
Some browsers like AOL automatically compress images so they load faster into the browser. The trade off is that they look exactly like you describe. This feature is especially helpful for dial-up users but rarely needed for broadband users. I haven't used AOL for a long time but there is a setting to disable compressed images.
Again, don't forget to clean your browser cache of Temporary Internet files: In IE it's Tools > Internet Options > Delete Files (not necessary to Delete cookies). Please read your browser help files for additional information.
If the things we've suggested don't work, contact your computer manufacturer. When you find a solution, let us know if you have a few moments.
