Which file extension does the image have?

[Marmar202]

Hi there, I want to use your respiratory in a part of my research program, I downloaded all the requirements and installed the Octave, also I downloaded a sample DEM and an image, put them in a directory and ran "python georef_webcam.py in_dir out_dir",

The first question appeared as you mentioned "Do you want to create a new set of projection parameters? y/n", I entered yes, but after that this message appeared: Which file extension does the image have? I entered JPG because my image is holding a JPG format. then I'm getting this message: No file with this file extension (jpg) could be found.
Stop program

What should I do??
Any help would be appreciated

you have to enter it in small 'jpg' and use full directory path if using windows. else for ubuntu you can use relative directory paths
