Center the enlarged image in screen not in the frame?

I am using jQuery Image Magnify v 1.11.

The enlarged image is centered in the frame and not in the center of the screen. I am using frames.

Is works fine in the single site without frame:

But not in the builted in frame:

Thank you VERY much.

I tend to get jobs that Im not very knowledgable on, done very ghetto, but they always seem to work. If I were having this issue I would probably just make the iframe bigger, in which case the pictures (assuming theyre left aligned in the iframe) would move to the left more. Mess with the alignment and it shouldnt be hard to figure out. Wont just left aligning the images (within the frame) fix your issue? Even if you have to make the iframe smaller in width?

It is not the width that´s the problem it is the height. The enlarged image is shown to far below. In center of the frame to low and not in the center of the screen.
