How to Add image caption?

I was searching around for the same and thought I’d share what i found in case anyone else was looking for it, here is a useful link I found.

https://pippinsplugins.com/retrieve-attachment-id-from-image-url

I used it to get the attached Image ID through the URL.
For me, i only needed the Title of the image which was easy once you had the ID. But you’ll have to mess with it a little to match your needs.
