@unalaydin, as already referred to previously,

a) We want all cuts to include a little bit of collar. At the same time, the ideal cut only contains 2-3 pixels beneath the chin. Since in some sources like this one, the person in the image may have a longer neck than usual, this would be quite difficult to achieve naturally.

Here's a video of the process on how to nudge the collar upwards:

b) when you have a lot of images to upload, then you should upload them as a pack instead of individually and save the both of us some time.

You can also upload up to 50 images per pack instead of just 6 when done individually.

c) It makes little sense to re-upload images already in the megapack 😕
