If there is the only one image in the document, there are 4 possible cases

(in all cases StartNo=EndNo=0)

1) Image is selected from left to right

StartOffs=0 EndOffs=1

2) Image is selected from right to left

StartOffs=1 EndOffs=0

3) Image is not selected (caret before it)

StartOffs=0 EndOffs=0

4) Image is not selected (caret after it)

StartOffs=1 EndOffs=1

I just tested: in (1) and (2) GetSelectedImage<>nil, in (3) and (4) it is

nil (as it's expected)
