@wyli I tried modifying the docs/conf.py to include this:

# If there is a + in the version, that means that we're not on a tagged version.
# In this case, we'll use the URL to the `main` branch. If we're on a clean version,
# then use that tag.
if "+" in monai.__version__:
    doc_image_url = "https://github.com/Project-MONAI/DocImages/raw/main/"
else:
    doc_image_url = "https://raw.githubusercontent.com/Project-MONAI/DocImages/" + monai.__version__ + "/"


rst_epilog = f"""
.. |DocImageURL| replace:: {doc_image_url}
"""

and then |DocImageURL| can be accessed inside the .rst files. Unfortunately, it seems that in sphinx, you can't do variable substitution inside of another directive. So .. image:: |DocImageURL|transforms/BorderPad.png is taken as a literal, and the variable is not substituted. See here for same problem, which doesn't look its easy to side-step...

Hi @rijobro ,

@wyli and I are in the national holiday, will try to review ASAP soon.

Thanks.

BTW, maybe I missed some context discussion, may I know why the dict transforms use colorful images and array transforms use black & white images?

Thanks.

@Nic-Ma I used colour for the dictionary transforms because they have the segmentations overlayed. The underlying MR image is black and white in both cases. Let me know if you find it unclear and we can discuss something better.

@Nic-Ma , and you're right. There's something wrong with all the num_samples=8, I'll check that.

Got it, thanks!

Sure, please also take a look other crop-samples transforms, maybe they are also not correct.

Thanks.
