If you wanna change the image or edit the image, You can delete that particular image or images and replace with the new one in the same name and the same album where you deleted the image or images.
That's exactly what I tried to do, however I'm not sure how to keep the newly edited image's name the same so it doesn't affect any previously linked posts!
I have cropped images, for example, and requested the cropped image to replace the original. This resulted in that image being "unavailable" for a previous SB post, which of course I will never do again! (I promise!!!)
On another note, PB does NOT seem to have a very detailed "options" menu. It sure would be nice, for example, if PB asked you, after editing an image, "Are you sure? Changes may affect links to the original image...here's how to avoid this: ...."
I have several scans on PB of the same cover (late night upload frenzy) and I want to delete the duplicates....but I can't tell which exact photo is linked to an SB post I made!
And PB does NOT like multiple edits done over two or more different times; the result is often a revert to the original scan with cropping and other improvements immediately lost!
I have tried using different browsers just for fun, seems to make no difference.
