Hey Cruz.
If you don't detest negative feedback (sorry about that, but it's meant in a constructive way), there's in my eyes an issue with your site.
I don't remember how it's called, I've also had it with some linux image viewer programs...
To describe it, it's the idea that we scroll down to view the bottom of an image... hit the button to move to the next image... and the next image is loaded from the previous image's last scrolling position, thus from the bottom.
And it's unfriendly, picture us reading, we scroll down to the bottom of an image, hit to view the next image... but we must first scroll up to view the image from the top.
No idea if it's doable, but if you could add, when we hit the previous/next button, a command to position the window back, it would be good.
Good luck with your site, I wish you well
