Regarding image generation, when choosing openai , an error occurs. The inspected error is as follows:

  File "/app/backend/open_webui/routers/images.py", line 681, in image_generations
    raise HTTPException(status_code=400, detail=ERROR_MESSAGES.DEFAULT(error))
          │                                     │              │       └ "Invalid value: '512x512'. Supported values are: '1024x1024', '1024x1536', '1536x1024', and 'auto'."
          │                                     │              └ <function ERROR_MESSAGES.<lambda> at 0x7fdf56308860>
          │                                     └ <enum 'ERROR_MESSAGES'>
          └ <class 'fastapi.exceptions.HTTPException'>
fastapi.exceptions.HTTPException: 400: [ERROR: Invalid value: '512x512'. Supported values are: '1024x1024', '1024x1536', '1536x1024', and 'auto'.]

It is necessary to manually change 512x512 to one of the supported parameters.

Indeed different models support different params.
