Get data from Images in asset manager

[janwillemwilmsen]

Hi, Is it possible to get the probe-image-size results from image urls like this: https://www.debijenkorf.nl/content/dam/images_debijenkorf/webshop/campagnes/creatieve-campagnes/2022/zomer/hero/flight-2/home/1.1_home_topbanner__hero_celebratelove_flight2_5120x1700.jpg.gravity/780x312-49.3880489560835x42.3160173160173

Because of the parameters after the .jpg a different size and focus is dynamically generated from the base image (https://www.debijenkorf.nl/content/dam/images_debijenkorf/webshop/campagnes/creatieve-campagnes/2022/zomer/hero/flight-2/home/1.1_home_topbanner__hero_celebratelove_flight2_5120x1700.jpg).

I get an error when probing the url with parameters after the filetype. Wondering if should create an exception in my application, or if this use case might be something to add in probe-image-size.

CLI:

./support/dump.js https://www.debijenkorf.nl/content/dam/images_debijenkorf/webshop/campagnes/creatieve-campagnes/2022/zomer/hero/flight-2/home/1.1_home_topbanner__hero_celebratelove_flight2_5120x1700.jpg.gravity/780x312-49.3880489560835x42.3160173160173

As far as i see, server returns 403 status (fobidden). That means it does not like request. Usually, that means extra restrictions, based on

• user agent
• ip address
• referrer

If you wish to investigate, i'd suggest to inspect firefox headers, and create the same list for prober request. Then repeat requests and drop headers one-by-one until find what is critical for that server.

With high probability problem is with user agent.

Thanks for your answer Puzrin! Good to know 'probe-image-size' would normally recognize file extensions with additional values(.jpg.gravity/7...).

Took the headers of an image which got a good result in the probe (https://www.debijenkorf.nl/content/dam/images_debijenkorf/webshop/system/Thuiswinkel_Waarborg.png) and added those to the probe script, dropped headers and changed many of them. But no luck so far. Think Cloudflare is detecting Playwright. Strange thing is that only images with parameters give an error, and the images without extra values after the filetype end up giving a good result.

One question about the cli : could you describe how to run it? I am on Windows.

• Made a folder in my project /support/
• Copied dump.js from your repo into the folder
• Ran the command in terminal

No luck. Hope you can share some pointers.

Clone the repo, then run npm i to install dependencies, then run dumper script with desired params. That's a standard way for all nodejs projects.

Oke thanks!

Played around with the CLI, tested other images with and without parameters. Found that adding a file extension after the parameters the probe did succeed.
