Image Appears All Stretched

The full version is different from the previews I'm seeing... That is, a different photo

Are you uploading with more than one window/tab open at once?

You will need to reload the image I'm afraid.

oh that is weird: the green framed preview on the stretched exterior image of the library is showing me an entirely different image, namely of the interior of the library.

OK, I checked again, it actually taken the image of another upload, because when I go into edit I'll see the correct image! So it's just the display photo that's wrong.

I have had this issue of images getting mixed up (not the stretching) when I had different images titled the same thing and uploaded them the same day. Such seems to be the case with your two images titled "Birmingham Library." My recollection is that I had to reload and rename one of them. Since I name them in PSE, I had to go back and rename it there, then save as a new file and then reload.

Thank you everybody, especially Joseph! I did what you said, I uploaded it again and renamed it and that worked! Thank you!!!! :-)
