Hi @AndrewWhyte ,
Were you able to solve this problem? I have a very similar problem: With ArcGIS Runtime, I need to display a .jpg file and I have the relevant .jpgw file in the same directory with the same name. However when there isn't a .aux.xml file present, I cannot display the image in the map. Is there a way to display it without the aux.xml files or is there a way to create this file automatically?
My question about this issue:

Thanks.
