Hi paidion hope all is well
See this post Beginner: Following the download.ipynb for creating a dataset and other posts on downloading images using Javascript.
Create you own data sets, upload them, skip the Azure part in the notebook and proceed to this section.
dest = 'images/grizzly.jpg'
download_url(ims[0], dest)
Also Look at how the dataset and images are used in https://github.com/fastai/fastbook/blob/master/04_mnist_basics.ipynb for the 3, 7 classifier.
cheers hope this helps
