that's the case here as well

But I'm selecting the image by just clicking on it.

If it was not selected before then

StartOffs=1 EndOffs=1 if the caret was behind the image and

StartOffs=0 EndOffs=0 if the caret was before the image

If I click it again when it's already selected then

StartOffs=0 EndOffs=0

All result in GetSelectedImage = nil, but the image is clearly visible

selected.
