IIIF image issue about dezoomify-rs

[awtur]

@MrChrisWin
On any page with the zoomable artwork, open the Chrome browser Developer Tools, go to Network Activity, and within the "All" tab, find and click on "default.jpg". Under the Request Headers, look for "x-jstor-access-session". Below is an example of how I use it with dezoomify.

dezoomify-rs -H "x-jstor-access-session: H4sIAAAAAAAAAJWTS2-bQBSF9_kViHWw5s1MV7WJI3WTRLazqK…3Kyj0_vpbVz8fbm9Fb-RLJPJq05Pughd0UF4ff89tBN8UEAAA" https://stor.artstor.org/iiif/fpx/sslps/c7731863/18890801.fpx/info.json "Ben Shahn illustrations/untitled _0.jpg"

Hello,

• This page in dezoomify's wiki explains how to get the full size image by modifying the URL
• The full IIIF protocol is described here
• If you get 401 errors, you will most likely have to set custom HTTP headers to request the tiles. dezoomify's wiki has a page about accessing protected pages. Once you've figured out which headers are necessary to avoid the 401 response, you can also set them in dezoomify-rs by setting a flag on the command-line when launching dezoomify-rs:

dezoomify-rs -H "HeaderName: HeaderValue" my-url

Thank you! Just had to specify full/full/
Honestly had no idea those wiki pages existed. Thanks for all the work you put into documenting this!
I would add a link in the ReadMe to refer readers to the older dezoomify wiki.

You're right, I will do that

Hi again. The full jpg approach is now giving 401 errors, however I found the appropriate header (access cookie) to add before the json URL for authorization, so the dezoomify option works. Do you know if this cookie can also be appended to the .jpg URL or somehow embedded into the browser? (something like ...full/full/default.jpg?cookie=...). I looked at the IIIF protocol, but couldn't identify a solution like this.

Autur, where did you find the access cookie and how did you modify the url path? Thanks.
