So here are a few useful nodes I have needed while building different workflows. Lets break them down

List length:

gives you the length of the list of images added

rgba video combine:

gives you a gif with an alpha layer applied, background remove images or segment them first for this to do much

clip strings:

why have 2, we can have a single clip input and a positive and negitive prompt from one box

file reader:

great for always reading the content of a file, so say you have a different application modifying it (like twitch chat) that can be used to directly influence different parts of the graph with this reader.

string concat:

simple string concatenation

image selector:

selects an image from a list of images. Can be the first, last, or a random image

image text generator

uses a llm that I host locally, but the node can be modified to allow you to call your own llm if you have one
