fix(backend): Implement passed uploaded media support for AI image customizer block

[Torantulino]

• Added store_media_file utility to convert local file paths to Data URIs for image processing.
• Updated AIImageCustomizerBlock to utilize processed images in model execution, improving compatibility with Replicate API.
• Added optional Aspect ratio input to AIImageCustomizerBlock

This change enhances the image handling capabilities of the AI image customizer, ensuring that images are properly formatted for external processing.

Note

Preprocesses input images to data URIs and adds an aspect_ratio option, wiring both through to Replicate in AIImageCustomizerBlock.

• Backend
  • backend/blocks/ai_image_customizer.py:
    • Preprocesses input images via store_media_file(..., return_content=True) to Data URIs before invoking Replicate.
    • Adds AspectRatio enum and aspect_ratio input; passed through run_model and included in Replicate input.
    • Updates block test input accordingly.

Thanks for this improvement to the AI image customizer functionality!

Your implementation looks good - I like that you're properly passing the user_id parameter to ensure proper security controls, and the enhancement will definitely improve compatibility with the Replicate API.

Before this can be merged, please:

1. Complete the checklist in the PR description
2. Add a test plan describing how you've verified this functionality works
3. Expand the "Changes" section to provide more details about what you've modified

Specifically, for the test plan, consider including steps to verify that:

• Images are properly converted from local paths to data URIs
• The AI image customizer works correctly with the processed images
• Any edge cases (large files, different image formats) are handled properly

[AutoGPT-Agent]

Thank you for your PR enhancing the AI Image Customizer functionality. Before this can be merged, there are a few issues that need addressing:

1. Incomplete PR Description: While you've provided a brief overview of what was changed, please expand the description to include more details about why this change was needed and what specific problem it solves.

2. Checklist Not Completed: None of the checklist items have been checked. Please complete the checklist by checking off all applicable items. At minimum:

   • Check that you've clearly listed your changes
   • Create and document a test plan
   • Confirm you've tested according to that plan

3. Missing Test Plan: Please add a specific test plan explaining how you've verified that your changes work correctly. For example, describe how you tested the image handling with the Replicate API.

Once these documentation issues are addressed, the PR looks technically sound and within scope of the stated changes.

Thank you for submitting this PR to enhance the AI image customization functionality! The code changes look reasonable and I can see you're properly handling the user_id parameter in the function calls.

However, before we can proceed with merging, please complete the PR checklist in the description. None of the checklist items are currently checked off, which is required by our process.

Specifically:

• Check off that you've clearly listed your changes
• Confirm you've made a test plan
• Provide and check off the steps in your test plan

Since this is a functional change to how images are processed, a test plan is particularly important to ensure everything works as expected.

Once you've completed the checklist, we'll be able to continue with the review process.
