ECW file support for templates

[M0OJM]

ECW files are ideal for satellite imagery such a Google Earth and they are much smaller than tiffs. It appears GDAL supports this format but they do not seem visible when I try to use them as a template in OOM. Am I missing a trick?

GDAL can be used together with a commercial software development kit (SDK) which adds the actual ECW support. But this SDK is a closed-source commercial product. It cannot be combined with open source software under GPL3 license.
