Ohh yes, there is a parameter to limit the ScrollZoom. But again! if you have no specific file resolution, this won't work for all pictures. But of course it is better than nothing.
To add the parameter, unfortunately you need a coding change. We didn't include that parameter to plugin parameters, because in case of wrong usage, it might messed up the zoom entirely.
Open this PHP file;
/plugins/system/flexibleZoom/flexibleZoomEffect.php
find this expression:
scrollZoom : ".$zoom_scroll.",
(there is only one place you can find it. (line#102nd) and right next to it, add this expression:
So, eventually it will look like this:
scrollZoom : ".$zoom_scroll.", minZoomLevel: 0.7,
(don't get confused with the name of the parameter. It behaves as "maxZoomLevel" for the ScrollZoom. If you decrease number, the zoom level allowed is increased. (for instance 0.3 is almost the default value) but if you increase it and make it around 0.9, the zooming level will stop around x2 which is where optic zoom is supposed to end. So there won't be any scrollZoom.
So i would suggest you to start from 0.3 and increase it one-by one until you get the best result (because the optimum value will depend on large picture and thumbnail resolutions difference) Probably the 0.5 or 0.55 would be the optimum value you need.
