I have a number of orthophotos as jpg files which I have georeferenced in ArcGIS. I have tried to open these in QGIS and they open as ungeoreferenced JPG's apart from re georeferencing them is there another workflow I should be doing.

If the files are .jp2 (JPEG2000) the georeferencing is built in. Otherwise, you will need the .jgw or.jpgw (World File) for QGIS to understand the georeferencing. If you do not have the World File the .jpg image will be dumb. Do you still have access to ArcGIS, as you may be able to either create the World File or save as .jp2? If you have an ArcGIS .aux.xml file associated with the image, this may have the georeferencing information, in which case you could construct a World File. I am not sure if QGIS understands.aux.xml files.

Thanks for your advice - I am running ArcGIS (as I am transiting to QGIS) so I can save the plans with a world file and hopefully that will work. Thanks Mark for the tip about georeferenced photos from cameras as well.

Cheers
