How to show exif data on mouse over?

This thread addresses it in part: https://www.ads-software.com/support/topic/data-on-one-line?replies=5

It deals with displaying data on one line. Once you have that and remove the paragraph HTML from the settings you can use the shortcode within the title attribute of your images. Last time I looked into it I couldn’t find a way to do that automatically when inserting the image into the post, you need to copy and paste the shortcode into the image title.

This post deals with doing the same thing, but automatically for gallery images: https://www.kristarella.com/2012/09/exif-in-wordpress-gallery-image-titles/

If you know javascript you can also do it that way, but I haven’t yet written out a tutorial for that.

Awesome! Will read up those threads after the weekend. Thanks for the pointers. Will reply back here once I’ve had a chance to read those threads.
