Access image part of siteinfo only if $siteinfo["images"] is actually set. The current
code didn't check this so I was getting an error Warning: Invalid argument supplied for foreach() in /home/vasudev/Public/friendica/mod/parse_url.php on line 305 Implemented a check before accessing $siteinfo["images"] with this commit and now warning doesn't come when giving URL of a site which doesn't have image from link button of post area
