@Maverynthia: Google Images works fine for me. It is the most heavyweight plugin, since it uses a complete browser instance, which runs in a separate worker process, the error that you posted means the worker process is not responding. The only way I know of for that to happen is an antivirus to block the process for suspicious activity, other than that, I'm out of ideas. THe code itself times out if google does not respond:
