The image layer system works pretty well with ECW images. I had a try by adding 114 ECW images (10000x10000 pixels each) into the catalogue and they can be used just fine together. Images take totally 6.6 GB on the disk and OpenJUMP seems to require 36 MB memory for showing the whole layer. > > There is now some inconsistent features with image loading. > It is possible to read any jpeg and png image and they will > be located at (0,0) if world file is missing.
