Updated to use the even simpler version of Save Image (Extended) which also allows for dragging and dropping .jpg files directly into ComfyUI. The reason being is that .jpg are much smaller on average than .png and most AI images don't include empty space.

"This custom node is largely identical to the usual Save Image but allows saving images also in JPEG and WEBP formats, the latter with both lossless and lossy compression. Metadata is embedded in the images as usual, and the resulting images can be used to load a workflow."
