Python Script to convert Image into Byte array

Question

I am writing a Python script where I want to do bulk photo upload. I want to read an Image and convert it into a byte array. Any suggestions would be greatly appreciated.

Answer 1

with BytesIO() as output:
    from PIL import Image
    with Image.open(filename) as img:
        img.convert('RGB').save(output, 'BMP')                
    data = output.getvalue()[14:]

I just use this for add a image to clipboard in windows.
