 For input, you need two PNG images of the same dimensions named e.g. `filename_0.png` and `filename_1.png`. You can then run `./run-torchwarp.sh filename` to run all the steps and output the morphing animation as `morphed_filename.gif`.
 
-You can also use `./run-stereogranimator.sh ID` with an image ID from [NYPL's Stereogranimator](http://stereo.nypl.org/) to download an animated GIF and run it through the morphing process.
+You can also use `./run-stereogranimator.sh ID` with an image ID from [NYPL's Stereogranimator](http://stereo.nypl.org/) to download an animated GIF at low resolution and run it through the morphing process.

+If you sign up for [the NYPL Digital Collections API](http://api.repo.nypl.org/), you can use your API token to download high-resolution original images. The `nypl_recrop.rb` script reads the token from the `NYPL_API_TOKEN` environment variable, and takes a Stereogranimator image ID as an argument, downloading the original TIFF image and using `template_matching_multiscale.rb` to calculate the crop and split the image into two views at full resolution. The `run-stereogranimator-hi-res.sh` script uses this process instead of `wget` with low-resolution GIFs. You can also pass the `NYPL_API_TOKEN` environment variable [in your `docker run` command](https://docs.docker.com/engine/reference/run/#/env-environment-variables).
