Hi Elise. Thanks for the reply.
This is great but of course I don’t want to be updating core files. I’ve had a look at that bit of code and I can’t see a way of using a filter.
I imagine changing this in a future update isn’t as simple as changing that code, as it would effect everyone relying on the attrachment title. Perhaps an option (in the widget) that allows the user to pick between the two?
I only suggest it because it really feels like the caption should be used for the caption 🙂
Thanks again
