Zooming not into cursor's location plus missing hand feature

[arasharchor]

issue1

when it is need to zoom into an image, it seems zooming goes to a point in the left corner of image regardless of position of mouse cursor. Also hand feature is missing using which one can move the image. So one has to use sliding bars to move the image or using arrows which both are not the efficient ways to do so.
