+## Digicam is telling me that my selected image is not supported.
+ - Digicam only supports "baseline" (not "progressive", or "interlaced") JPEGs. Here are some tips to make your photo compatible:
+   - Using Photoshop:
+     - Go to File > Export > Save for Web (Legacy)
+     - Change the format to JPEG. Make sure to uncheck 'Progressive' and 'Optimized'.
+   - Using Paint.NET:
+     - Simply save your image as a JPEG. Paint.NET does not support progressive JPEGs.
