I was wondering how it’s possible to reuse existing (uploaded) images in other posts and, more importantly, as
og:image (Facebook) and as “post image”. Actually, when you go to these settings, it just lets you upload an image from computer, making you upload the same file twice (once inside the post and then as post image).
Also, if you click on the recycle bin and remove the image, the only way to put it again is… to reupload it. I don’t know if there are solutions, but the actual system isn’t optimized at all.
