This repository contains all CIL public annotation metadata in the JSON format.
Let's take CIL_10725 as an example.
If $json->CIL_CCDB->Data_type->Video is set to be TRUE, then you can download the following files:
https://cildata.crbs.ucsd.edu/media/videos/10725/10725.jpg
https://cildata.crbs.ucsd.edu/media/videos/10725/10725.flv
https://cildata.crbs.ucsd.edu/media/videos/10725/10725.zip
Otherwise, download the following files instead:
https://cildata.crbs.ucsd.edu/media/images/13007/13007.jpg
https://cildata.crbs.ucsd.edu/media/images/13007/13007.tif
https://cildata.crbs.ucsd.edu/media/images/13007/13007.zip
There are alternative or supplemental files. You should check whether $json->CIL_CCDB->CIL->Alternative_image_files object exists. If so, You should take value from $json->CIL_CCDB->CIL->Alternative_image_files->URL_postfix and add "https://cildata.crbs.ucsd.edu" as the prefix.
Take CIL_45701 as an example,
