I am working on a Windows Forms Application (in C#) to flash an OS image to external storage devices like a USB Stick or an SD card. My code works for images in the ISO format. I am now looking to support images of IMG format as well.
I could not find satisfactory resources on the web explaining how data is stored in the IMG format. Any references to code or text on this topic will be useful.

Image Mastering API states that it only supports three file system formats: ISO 9660, Joliet, and UDF. For IMG images, you can refer to Disk Image Processor or Genimage for more information.
