This is going way off topic but never mind...

I'm glad that worked for you, there are some benefits to being a sad technology obsessed geek :-)

OK the values do the following:
0 - Never send the Referer header.
1 - Send the Referer header when clicking on a link.
2 - Send the Referer header when clicking on a link or loading an image. (Default)
As you have already seen some sites block images from being loaded if you don't have the right referer string this is usually to stop people using copyrighted images on one server in pages served from another server. This is very useful if you have limited bandwidth. Most websites that do this match against a specific URL and reject anything that does not match, including a missing field, we are lucky that the site used by Petz does not do this. From this description I hope that you have worked out that if there are now websites that you visit that have missing images it is due to this change and you should set the value back to 2.
There are some websites out there that use the referer field to do tricks like creating dynamic back links on the new page that you visit, this will work with the value set to 1 or 2 but not 0.
If you are paranoid about sites knowing where you have come from leave this setting at 0 and appreciate that some bits of the web may become that bit less friendly to you ;-)
