Hi @petarvujovic98, thanks for submitting this issue. Could you check the format of your image? What is the exact extension of the image?
Here is an example of how to make a simple transcript of an image using
gpt-5.1-codex-max:https://github.com/user-attachments/assets/bfd871d2-4943-4afb-b5ed-a637cdb45ed6
This image has been generated by the screenshot function on Mac. Hope this helps :)
I tried with svg first, then with png, and neither worked
