"## Kill Transparency with Black\n",
"----\n",
"\n",
"This Python script utilizes the PIL (Python Imaging Library) to recursively traverse a specified directory, identifying image files with extensions `.jpg`, `.jpeg`, or `.png`, and adds a black layer behind the main layer of each image, effectively removing any existing transparency, before overwriting the original files with the modified versions."
