[mapguide-users] RES: How to display PNG images

[Gordon Luckett]

Most images in MapGuide require a georeferencing file or World file.

For JPG you may have to create a JPW
(check out this
https://iric-gui-user-manual.readthedocs.io/en/latest/06/09_georef.html or
google JPG world files)

The json should be enough to create the file.
