ValueError: not enough values to unpack (expected 3, got 2)

Which image format are you trying to use?

@kelvins I'm encountering the same issue, and currently using the jpg format. I know you mentioned in another issue that we should use png, but care to explain a little as to why this is happening?

@prophet6250 I would imagine it has to do with the encoding/decoding of the file formats. The program handles a particular file format and data structure, adding compatibility would be possible, but would require exception handling, and conversion of .png to .jpg before embedding anything.

"ValueError: not enough values to unpack (expected 3, got 2)" tells us the expected minimum values weren't given, probably due to the difference in file formats, but the ValueError error handler can be used for the exception handling, file conversion if the error occurs, and the format of the file determined.

Also, "r, g, b = rgb" is the value it's trying to assign, but it's only received two values.
