Thank you for your post!
The app currently supports the import of GeoTIFF (.tiff, .tif file embedded with geographic information) and JPG (.jpg) files that must be packaged with either a TFW & PRJ or JGW & WKT in a ZIP file. Are you on a version of AutoCAD that supports the export of GeoTIFF files? You’re missing the partner for both of the .tfw (.prj) and .jgw (.wkt) – is there any way you can retrieve these files? If you can try and manually create them, it may be possible to import them into the app so long as they are paired with the correct file and the .jpg in a ZIP file.
If you don’t mind sending those files to us we can take a look into this further. Feel free to contact us or send the files to help.avenzamaps.com.
All the best,
