 * Customize the folder, sub-folders, and filenames of your images!

-## Installation
-### Requirements:
-There is a requirements.txt that will take care of that, but just in case:
-
-- python 10.6
-- piexif
-- pillow
-- pillow-avif-plugin
-
-```
-pip install piexif pillow pillow-avif-plugin
-```
-
-For Jpeg XL / jxl it's more complicated. You need to install and compile the wheel jxlpy, and therefore, need a valid and functional MSVC installation.
-
-```
-pip install jxlpy
-```
-
-### Manual Download
-1. Open a terminal inside the 'custom_nodes' folder located in your ComfyUI installation dir
-2. Use the `git clone` command to clone the [save-image-extended-comfyui](https://github.com/audioscavenger/save-image-extended-comfyui) repo under ComfyUI\custom_nodes\

+## Miscelaneous
 #
 Disclaimer: Does not check for illegal characters entered in file or folder names. May not be compatible with every other custom node, depending on changes in the `prompt` object. 
 Tested and working with default samplers, Efficiency nodes, UltimateSDUpscale, ComfyRoll, composer, NegiTools, and 45 other nodes.
 
 #
-Quality and compression settings:
+Quality and compression settings: default is 75, 100 will activate **lossless** for AVIF and WEBP only.
 
-* AVIF quality is fixed at 60.
-* WebP quality is fixed at 75.
-* JPEG quality is fixed at 91.
-* JXL quality is fixed at 91.
-* PNG is maxed compressed (9)
-
-Start a discussion or a poll if you want to change output quality, and add another attribute in the node. There's so many already, some complain about the node being too tall.
+Quick comparison of size per extension, for the same picture, AVIF quality=60, WebP quality=75, jpeg quality=91 (and yes, AVIF still looks better then WebP):

-The prompt is included under the **EXIF** tag `UserComment` (IFD0 / 0x9286) as defined [here](https://exiftool.org/TagNames/EXIF.html).
-It is saved in this form: `UserComment = {"prompt": {"1": {"inputs": {...}}}}`.
+The metadata Are included under the **EXIF** tags IFD0 as defined [here](https://exiftool.org/TagNames/EXIF.html)
+
+| Data | EXIF | Name | String looks like |
+| --- | --- | --- | --- |
+| prompt | 0x9286 | UserComment | Prompt: {"5" ... } |
+| workflow | 0x010e | ImageDescription | Workflow: {"5" ... } |
 
 You can retrieve the prompt manually with [exiftool](https://exiftool.org/), here are some example commands:
-- `exiftool -Parameters -Prompt -Workflow file.png`
-- `exiftool -Parameters -UserComment -Prompt -Workflow file.{jpg|webp|avif}`
+- `exiftool -Parameters -Prompt -Workflow image.png`
+- `exiftool -Parameters -UserComment -ImageDescription image.{jpg|jpeg|webp|avif|jxl}`
 
+#
+ComfyUI cannot load lossless WebP atm. Feel free to try and fix `pnginfo.js`

 I won't promise you the moon, but since I use this node myself, I will maintain it as much as I can. I do provide a way to contact me, and will accept PR and collabs. 
 Once I feel like I don't have time to work on it, I will gladly transfer ownership or let collabs maintain it.
