In the attached dialog screenshot, I had to retry downloading the selected images (img_3494.jpg and img_3497.jpg).
In the attached digikam screenshot, you can see that img_3492.jpg was overwritten with the contents of img_3494.jpg, and img_3496.jpg was overwritten with the contents of img_3497.jpg. You can see in the dialog screenshot that those images are originally very different.
Another weird thing is that what should be img_3496.jpg is called in digikam img_3495.jpg. And the real img_3495.jpg is missing. In the case of img_3492.jpg there was no such mess. It is img_3492.jpg itself that is missing.

I hope you realise how serious this bug is.
