Description of problem

In the mobile version of the forum all the uploaded photos with servimg are shrunken.

In fact, the link is changed. Example:
https://i.servimg.com/u/f37/14/92/41/94/scherm50.png (original link)
https://i.servimg.com/u/f37/14/92/41/94/th/scherm50.png (thumbs link)

This doesn't happen if someone uses other hosting. But sometimes happens that there are images of different sizes (in fact, with imgur the images are not shrunken).

Is there a way to delete the "thumbs" image conversion in the mobile version? Theoretically it would be enough to eliminate the /th/ in the links.

Thanks
