Since the update to 3.7.x an image title is no longer added to the image link when displaying a gallery. In version 3.6.1 and earlier the HTML looked like this:
<a href="http://title.to/image.jpg" title="Image Title">
On my site, when a visitor clicks the link, the image opens in Fancybox and the title of the image is used as the caption.
However, since 3.7.x the caption has disappeared and I noticed the HTML has changed into:
My PHP-skills are very limited, but I assume I could add some code to functions.php in my theme to add the title to the image link.
Anybody have any suggestions?
