Sometimes it is useful to have individual icons for external hard drives, macros or shortcuts. (On MacOS it is easy to exchange the default icon of an object by selecting Get Info, highlighting the icon in the top left corner by clicking on it, and pasting the new Icon onto it by pressing Command+V). Suitable images can oftentimes be found on the web (for example through google image search) whoever they are usually images that have the wrong size and are images rather than Icons. While there are tools like Image2Icon that allow to generate Icons from images, it would be great if this functionality could also be integrated into Resize Images by adding an additional output format (*.icns). https://en.wikipedia.org/wiki/Apple_Icon_Image_format
