Weird original size

Hi there,

First of all, great plugin! Saves me a lot of headaches ??
On most images on my dev site it seems to work great. However, on some of them the original size seems a bit off. URL: https://www.viamsterdam.com/dev/viamsterdam/case/friendsforks/

For example the image with the 2 spoons near the bottom. The debug log:

The image container size is 638 x 570, but for some reason chrome’s developer toolbar says that the “natural image” is 250px in height. I am using the rwp_img() function and the ID I have put in should be the right one for the actual original image, which is 800 x 550. Any thoughts?
