We primarily use the ECW format and not Mr. SID because we have ER Mapper.
To make SID files you have to us Lizard Tech's software since they hold the
patents on that file type. ESRI use to sell an extension for Mr. SID but
Lizard Tech has now taken over that as well.
As to the jgw file, that is just a world file for a georeferenced jpeg. It
is the same as a tfw for a georeferenced tiff. Map uses these files to
insert images in their correct geospatial location including rotation and
scale. I believe Terry explained how to do that.
