if you run the extension using WEB ACCELERATOR, please disable it because the images will be not calculated correctly. PHP doesn't use WEB ACCELERATOR and the images fetched are the same as the remote site.

Check your memory limit for PHP – News Feeder was tested under a server with the value configured to 72MB with image fetching enabled and thus the extension ran very slow. A value of 96 MB could be right to work correctly. If you have not access to server configuration (i.e.  hosting plan limited to 64 MB or less, consider to disable the download of images to reduce time and resources consumption).Please inform me if you face problems: at(at)uniud.it
