I noticed something similar. I asked it extract a guid from an image and it wrote a python script to run ocr against it...and got it wrong. Prompting a bit more seemed to finally trigger it to use it's native image analysis but I'm not sure what the trick was.

Probably just ask it to use native image analysis versus writing code. I have done this before extracting usernames from screenshots.

I've run into this with uploading audio and text files, have to yell at it to not write any code and use it's native abilities to do the job.
