Image Viewer Bug with full resolution image

When viewing images, first a preview is displayed and after a short time a request ist made to load the full resolution image. This request does not get cancelled if I go to the next image. This results in the previous image being displayed at full resolution, even though I am already vieweing the next image's preview. Depending on how fast I go through my images, it might even mean the 3rd or 4th last image is suddenly displayed, which is pretty confusing for the user. It might be better to cancel that request for the full resolution image if the user goes to another image, or at least check if we are still displaying the preview before showing the full resolution.
