Before the last upgrade to uploading photos into your post, actually the upgrade before yesterday, I used to be able to hover the curser on a photo already in the blog post and the photo id number would appear. Now that doesn’t happen, there seems to be no way to determine any reference number to a photo I’ve taken out my own photo library. Am I missing something?
If you click on the image in the post editor you’ll see its ID number in the “Path” line right below the edit box.
If you go to Media > Library, hovering over a thumbnail will display its ID number in the progress/status bar of the browser, as before, and clicking on it will display the ID number in the address bar of the browser, as before.
