Is caption display for single images not available as a feature or as a bug? I’ve just now noticed that none of the single image posts that I use SB on display SB captions, but gallery SB images display them fine. I’m not certain if its always been that way and I just didn’t notice it before.
In your html code check to see if you have "title" attribute inside your <a … > tag. That’s what SB is looking for to display caption. When I add single images, there is no title tag so I have to go and manually add it in the code so it would look something like <a title="blah blah blah" href="….>
See my post below – there should be a way to pull title tag from the <img> if none is available in <a> tag but I can’t seem to find that piece of code in SB2.
