ECW images in ArcMap

Hi Peoples,


Much of our image library is in ERDAS ECW format.


What we have found is ArcMap is not displaying the images with the clarity it should.

When we take the same image, convert it to JPEG2000 and display in ArcMap – it looks much as it should.


We downloaded and installed the ERDAS ECW Plug-in for ArcGIS Desktop 2015.


Great result – the images in ArcMap looks as they should.


When we build mosaic datasets though, the building of overviews fails.  We get the old checker board of black and white tiles as it appear to have no reference to the images.


Anyone else seeing issues with ECW images in ArcMap.
