Can you give me some more detail on what you mean by "URLs from the Chibis"?
The chibis are images, if you open them as a new tab (using the option from the right click) you can see the URLs.
Opening them in a new tab doesn't work for me, since the option doesn't come up, but here's the link to a base 64 decoder/encoder:
