I'd start with a simple suggestion: a list for all the default short codes either on your blog, faq or on the plugin itself would be mighty useful
Now my problem.
Links don't seem to show up properly using the default short code (which I had to find in the changelog after I came across an old link hack post where someone noted the new link feature, hence my above suggestion)
Say I use this code, following the changelog:
[singlepic id=32 h=100 float=none link="google.com"]
the link would appear as homepage.com/"google.com"
This is fine if I want to link to a local post, but what if I wanted to link out? Does it mean I have to create a local redirect? Or am I using the shortcode wrongly?
