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.

## Prompts
The workflow includes some basic propmts. Prompts are split into 2 types, positive and negative. <imgsrc="./wyrde was basic prompts.png"width="80%"align="middle">
* Positive prompts are what what you hope to see in the result.
- (Positibe prompts are often referred to simply as _prompts_, but sometimes _prompts_ means both positive and negative prompts. Confusing? Welcome to Stable Diffusion!)
* Negative prompts are items which the user hopes **don't** show up in the result.
* There are all sorts of guides on making good prompts.
- Basically, a good prompt has a subject and conditionals.
- Subject is the main thing desired in the result, such as `adorable cat girl wearing a striped bikini`
- conditionals are further details about the subject or the _type_ of image desired. `detailed eyes, detailed hair, pastel hair,` give further detail about the subject.
- `absurdres, vibrant, photograph, photographic photo, photogenic, rule of thirds, anime, illustration, medium shot, Azulejo, finely detailed, realistic, masterpiece, best quality, illustration, soft focus, HDR 8K, artstation, pixv, unreal engine 5, SFW, ` is a bunch of information about the type of image desired.
+ as an aside, _Azulejo_ is a Portuguese tile which adds an interesting style to images with many models.
