It looks like 1.6.1 now automatically adds a rel=”slb” (plus some slb_group) to image links pointing to url’s ending in a known image postfix. While a nice idea in theory, this does not work well with links pointing to non-image content that ends in an image postfix.

Steps to reproduce:
1. Create an image link pointing to a picture page in Wikimedia Commons.
2. Try clicking the link with SLB activated.

What happens:
SLB tries to lightbox the Commons page.

What I expect to happen:
I’d expect SLB not to mess with the link so that when I click the image, I’m taken to the Commons page as usual.

Other notes:
I don’t think there’s any way around this other than disabling the automatic rel=”slb”’ing feature entirely (which the plugin currently, AFAICS, doesn’t allow me to do). There’s no reliable way to determine a link *really* points to an image just by looking at the url.
