Infocklick - zoom to embedded images / similar to zoomify tool

[JakubPelka]

Problem: If you want to add en image in documenthandler or in the infoclick you have to scale it to the proper size, or resize the window to see whole image. For example if you have a point layer with drone images or some single aerial images looking on those in 800x600px is pointless. I am aware we can have a link to "download in full size" but this might be problematic too when you don't know if you really need to download a file

Solution: In OpenLayers there is "zoomify" tool: https://openlayers.org/en/latest/examples/zoomify.html if we can place it or something similar into documenthandler or infoclick to make it possible to zoom into image it would be really good solution. Initial size of window can remain the same, but we can inspect images properly.
