Is this OK?

[Toastberg]

Just wondering, is it alright to put pets in our sig with only the image and not leading anywhere? Everyone here obviously knows where the pet came from but I don't really want to get anyone angry at me because I didn't put the URL.
My reason is I wanted to fit more other clickies in there. As you can see.

I'm pretty sure it is okay here xD

Perhaps outside CS you should keep the link back, but here on the forums, I've seen lots of people do it and no one seems to mind ^-^ Because indeed, we all know where they come from xD

I'd say its okay.

I'd be pretty shocked if anyone couldn't work out where they came from
