It seems like only a couple of days ago that I was muttering about how WordPress 3.5 had stopped inserting the title attribute of images inserted into posts. While this was only a minor inconvenience, it irritated me enough to (a) moan about it and (b) try to change it.
I’d done a fair amount of reading, which led me to believe that a simple function (and it would have to be simple, given my coding skill level) should be able to do what I needed. One of the great things about WordPress is that it’s designed to be fiddled with. It offers numerous “hooks” and “filters”, which, put in the basic terms that a non-programmer like me can understand, allow you to change almost everything it does. Want to insert some extra text? Want to stop something displaying? Chances are that there’s a hook or filter you can use.
In this particular case, it seemed that what I needed to play with was the
filter. And after much googling, and much trial, and and even more error, I came up with a function that does exactly what I needed. As I didn’t want to break things, rather than adding it to my general purpose Functionality plugin, I created it as a shiny new plugin all to itself. And sure enough, with this plugin activated, when I insert an image, the title attribute is inserted. This ensures that the tooltip appears, and lightbox plugins no longer get confused.
It’s such a short and simple thing, that I can include the whole of it here:
This has only been tested on my own sites, where it didn’t appear to break anything. Use at your own risk. If you happen to be a real programmer, you may point and laugh as much as seems appropriate. Or if you’re a real programmer and you have advice or suggestions to improve what I’ve done, I’d be happy to receive them.
 Probably because it was
