I was looking for something simple, compact yet comprehensive enough to help deciding which LoRA epoch or strength is the most suitable, especially when using LoRAs based on real persons.
I know there are plenty of other versions out there but this is the version I'm most happy with. It uses the Image Concatenate Multi node which can be fed multiple version, spilling out one image with all iterations.
The Workflow can be used with other checkpoints too, given that the correct Clip and Vae is used.
PS: The Power LoRA Loader node is there just in case you need to test your LoRA in combination with others.
