# wyrde'a basic workflows
This is a workflow utilizing several WAS nodes.

## Switching nodes
The workflow uses noodles (the lines between nodes) to switch from img2img to txt2img and baked vae to loaded vae.
* To switch from img2img to txt2img, drag a noodle from the LATENT dot on the "_EmptyLatentImage_" node to the _redirect_ node in the blue box. (The old noodle is replaced.)
* Switch back by draging from the LATENT dot on the _VAEEncode_ box to the _redirect_ node.

Switching from baked VAE to loaded vae is similar. (Baked VAEs are included inside the model file.)
*  Drag a noodle from the VAE dot in the _VAELoader_ node to the purple _redirect_ node below.
* To change back, drag a noodle from the VAE dot in the _CheckpointLoaderSimple_ node to the purple _redirect_ node below.

## In stable diffusion, size does matter

When using img2img, images should be resized to better fit the model. Most models are designed for 512x512 _initial_ generations. 768x512 and 512x768 are also common.

Large images will also suck of VRAM and time during sampling for the first generation. Instead of creating a big image in stable diffusion, it is better to go through a process called Hi-Res Fixing. That's a subject for another time, but for this basic workflow, stick to smaller initial images. (This can easily be changed to experiment with.)

Back to img2img.
* Use the _Resize Image_ node. The node is initially configured to resize images to 512x768. It is best to crop/alter your image in another program so it it fits 1:1 or 1:2 ratio for easy scaling. (Nodes can be used to alter images, but that's a more advanced topic.) Doesn't matter if the ratio isn't perfect, the image is a guide. Closer the better though.
* The _node's_ "mode" can be changed from "resize" to "rescale" to easily reduce larger images as well.
