Support for uploading multiple images or provide detailed images to update the code

Hi team, appreciate your work which is awesome!

**Is your feature request related to a problem? Please describe.**
I ran it locally and played with it using Claude Sonnet 3.5 API, I found that the quality of generated code depends on the complexity of the provided image, for example, if I provide the screenshot of the whole page, the generated code can only show main sections of the page, but if I provide a screenshot which only contains the first section of the page, there is a higher degree of restoration. I tried to update the site using different prompts, it works, but it also need a lot of efforts to find and describe the different of generated page and original page.

**Describe the solution you'd like**
So I'm thinking whether it helps or not to allow us to provide an image of a specific section of the site and update it accordingly. The whole process will be:
1. Provide the complete image and generate the basic structure of the code
2. Update the code using images of different sections to achieve higher degree of restoration.
3. Repeat step#2 until we get a satisfied version and update the page manually.

**Describe alternatives you've considered**
An alternative solution is to allow to provide multiple images to provide more information to the model, not sure which solution is better.
