[fixed] Snap Image window suddenly close by particular image data.

[tkbd]

dgud,Thank you for many error countermeasures.

Afterward ,I also tested a lot of cases by changed on imported image file content, size, name ,formats etc.
Finally,I have identified the simple conditions under which this issue occurs.

I thought that may be due to the file order, not the file name.
I upload an image, the error reproducible steps and comparisons are illustrated below the image.
