+## Visualizing images in Jupyter
+We added support for visualizing images directly in the Jupyter notebook-like environments. When you load an image dataset, the images will be displayed automatically when you return them.
+
+```py
+from datasets import load_dataset
+
+ds = load_dataset("<path/to/folder>",
+                  split="<split>")
+
+ds[0]["nifti"]  # The image will be displayed directly in the notebook
