Summary 💡

Command Generate Image "generate_image" is a great addition. However the image size is hardcoded, I propose the issue to make it controllable with an optional argument image_size.

Pitfalls :

• Dalle has only 3 sizes "256x256", "512x512", "1024x1024".
• StableDiffusion works with multiple of 8 as valid size, but image may suffer loss of context > 512px.
• image_size argument should be optional and not make it more complicated to generate an image without specifying the size.

Examples 🌈

• Stable Diffusion Replica, size can be changed https://replicate.com/stability-ai/stable-diffusion

• Dall-e API https://platform.openai.com/docs/api-reference/images/create#images/create-size

Motivation 🔦

This will help the user to generate an image at the needed size.

I will push a PR in that direction.
