This is a simple repost of the thread with allowed image URLs which got lost somewhere:

Starting in vSide Beta 7 you can now use .jpgs from dozens of internet sites for picture frames in your apartment like photobucket and flickr. WOW
In Addition to Photobucket and flickr, you can use:
* *.myspace.com
* *.facebook.com
* *.wikipedia.org
* *.imageshack.us
* *.deviantart.com
* *.nasa.gov
* *.weather.com
* *.nationalgeographic.com
* *.timeinc.net
* *.yimg.com
* *.style.com
* *.lolcats.com
* *.espn.go.com
* *.ctv.ca
* *.warnerbros.com
* *.aolcdn.com
* *.cdn.turner.com
* *.seventeen.com
* *.msn.com
* *.starpulse.com
* *.americanidol.com
* *.elle.com
* *.eonline.com
* *.famousartistsgallery.com
How Does it Work?
Just grab any .jpg URL from any of the above domains and copy/paste the URL into your photo frame
* Let's say you are at the wikipedia page for Katy Perry
* Then you come across a photo that you want for your apartment, like this one
* Right-click on the image in your browser and choose: "Copy Image Location"
* In this case, you'll get a URL like this:
* Sometimes URLs will have extra stuff after the .jpg -- make sure to strip that stuff off; our example is OK.
* Click on a portrait in your apartment
* Paste this URL into the field
That's it!
