When developing a site, it can be useful to know the attachment ID of the image you’re looking at. I use it along with wp cli to regenerate specific thumbnails: wp media regenerate 1235
This adds a class containing the attachment ID to images, so you can right click and inspect element to know the appropriate ID.
