Hi @thinh-huynh-re ,
To implement a loading script for an image dataset, you can have look at the guide we provide in our docs: https://huggingface.co/docs/datasets/image_dataset#loading-script
Also note that currently the viewer uses the streaming mode, which passes URLs instead of local paths. However when passed a string, Image.open only accepts local paths.
To circumvent this limitation you could pass a file-like object instead, by replacing:
Image.open(os.path.join(dir_path, row["rgb"])).convert("RGB")
with
Image.open(open(os.path.join(dir_path, row["rgb"]), "rb")).convert("RGB")
for all the images.
