 The basic ones I'm interested in are these two. Let's just focus only on ` /sdapi/v1/txt2img`

 - When you expand that tab, it gives an example of a payload to send to the API. I used this often as reference.

 - "images" is the generated image, which is what I want mostly. There's no link or anything; it's a giant string of random characters, apparently we have to decode it. This is how I do it:
 ```
 for i in r['images']:
-    image = Image.open(io.BytesIO(base64.b64decode(i.split(",",1)[1])))
+    image = Image.open(io.BytesIO(base64.b64decode(i.split(",",1)[0])))
 ```
 - With that, we have an image in the `image` variable that we can work with, for example saving it with `image.save('output.png')`.
-- "parameters" shows what was sent to the API, which could be useful, but what I want in this case is "info". I use it to insert metadata into the image, so I can drop it into web ui PNG Info. For that, I'll backtrack a little bit and pull what I need, which is nested in "info"
+- "parameters" shows what was sent to the API, which could be useful, but what I want in this case is "info". I use it to insert metadata into the image, so I can drop it into web ui PNG Info. For that, I can access the `/sdapi/v1/png-info` API. I'll need to feed the image I got above into it.

 - Import the things I need
 - define the url and the payload to send
 - send said payload to said url through the API
-- when I get the response, grab png info from "infotexts" inside of "info"
-- then grab "images" and decode it
+- in a loop grab "images" and decode it
+- for each image, send it to png info API and get that info back
 - define a plugin to add png info, then add the png info I defined into it
 - at the end here, save the image with the png info
