I played around with the images to find more details about the Bug. Here is what I found:
- any picture taken with phone VERTICALLY (keep original image - unaltered) and then added to a listing, the image is not cropped and will display larger then the rest
- if you open the original image in Windows and you rotate it and just close the image (no save), then re-upload to the listing, it will display ok (no bug)
- if you take the picture instantly with phone when adding the listing, it will display ok (no bug)
- if original image (the vertical one) is resized in mb by any tool (email, social media, etc), it will display ok (no bug)
See attachment (instant picture vs previously taken picture). This will generate larger thumbnail, preview and normal image
I hope this info helps you in finding the solution of bug
