torchvision.transforms Images are incorrect

[MaxVanDijck]

📚 The doc issue

All the example astronaut images on https://pytorch.org/vision/stable/transforms.html show the same pad transform as shown:

Suggest a potential alternative/fix

Images should be changed to images that show the correct transforms

Thanks for the report @MaxVanDijck

The things you're showing aren't supposed to represent the specfic image transformations, they are just thumbnails that link to the example where each transformation is illustrated in more details.

I don't think sphinx-gallery supports having different thumbnails for different backlinks, that would involve a lot of manual work that we would prefer to avoid anyway. We can however change the thumbnail to make it more obvious https://sphinx-gallery.github.io/stable/configuration.html#choosing-the-thumbnail-image. I'm not sure which one would be best though. Perhaps the GrayScale image one, as it's bigger? (https://pytorch.org/vision/stable/auto_examples/plot_transforms.html#grayscale)

If you have a better idea we're all ear :)
Feel free to submit a PR as well if you're interested!

@NicolasHug Maybe rather than showing one specific transform we can use another image that makes it clearer that it is linking to the gallery? Such as a larger image with multiple different transforms shown for example one like so:

Using:

That sounds great @MaxVanDijck !

@MaxVanDijck just making sure, would you like to submit a PR for this, or are you OK for us to let someone else grab it? We're not in a rush so if you want to do it we can definitely wait a few days if needed

[MaxVanDijck]

@NicolasHug You can let anyone grab this issue!
