Improve image interaction

[PaulKiddle]

Currently, the specimen images move by reacting to mouse placement and, as there is no way to halt this movement, the image has a tendency to ‘flick’ when moving between the entry data side of the app and viewing the image – causing irritation.

A solution to this could be to enable image movement via mouse dragging only, which would enable the image to pause when no mouse click is registered. Zooming into the image requires clicking on the + and – buttons and, as these are on the image itself, it can easily cause the ‘flicking’ motion highlighted above.

An easy solution might be to enable zooming via the mouse scroll-wheel?

• Move image only on mousedown
• Zoom in/out on mousewheel (which direction? custom?)
• Double click to auto-zoom?
