I guess you could extract the bounding boxes for those images with gdal_info, 
but it would be much easier to set up a tilemill instance, load up a OSM 
bright style, then put the ECW images *on top* of that, so that they hide the 
underlaying OSM map.

Yup. In the world of geo, you need to use an array of tools, not a magical 
one-size-fits-all tool.

IMHO, one of your best bets is tilemill. You can load up some OSM extract, 
apply the OSM bright style, put some raster data on top (maybe convert those 
ECWs to another format to do so), then overlay your speed/accident data in 
another layer.



Best,
