> Hi @rootonchair ! Sorry for the delay. Indeed for backward compatibility and to work seamlessly with the MLlama model, this processor needs to process nested images. I just [opened a PR](https://github.com/huggingface/transformers/pull/38157) that improves support for image processor handling nested images, you can have a look here. Once this PR is merged, you can do something similar for MLlama than it's done for Idefics2/3/SmolVlm in the PR.

Sure @yonigozlan, I will proceed when your PR is merged

Hello @rootonchair ! The PR I mentioned was merged btw, if you want this PR another go!


@yonigozlan that's great. I will get back to this PR
