Hi – I am not sure what device you pulled these images from, as yes, those are correct. I am attaching a new set of the same image so you can see how it looks on a desktop browser window (resized to ‘mobile’) versus how it displays on an actual mobile device. You will see that it appears the image is being forced into a square (300×300) format versus the 300 wide by whatever proportional height. Thus rendering the image to look squished.
filename: correct proportions was taken from desktop running chrome with the window sized down to mobile width. This is how the image should display.
