Some images in description are returning HTTP 403 as a result of indirect requests

[James103]

Some of the images in the mod's description (https://modrinth.com/mod/horsebuff) are not loading, for the following reason:

• The images are being requested through a caching service, example: https://wsrv.nl/?url=https%3A%2F%2Fimgur.com%2FQTk8w33.gif
• These requests fail because the upstream imgur service has blocked the caching service: {"status":"error","code":404,"message":"The requested URL returned error: 403"}

Changing the URLs to fetch the image directly from imgur (https://imgur.com/QTk8w33.gif in this example) works properly.

I believe this is a case of modrinth caching my images for me, as my markdown already directly links to imgur as you suggested. You can confirm this yourself as the Readme.md here uses the same markdown as the one on the modrinth page.

I believe this is a case of modrinth caching my images for me

Can confirm this is the case. Checking the source code for the Modrinth backend, I find the following:

• There is a list of hostnames Modrinth allows directly serving content from, which includes i.imgur.com among others but not plain imgur.com.
• If the hostname of the URL does not exactly match one of the hostnames from the list, Modrinth prepends https://wsrv.nl/?url= to the URL, effectively forcing the image to be cached through a third-party service instead of being served directly.
• From my own testing, links of the form https://imgur.com/QTk8w33.gif redirect to https://i.imgur.com/QTk8w33.gif (the hostname changes from imgur.com to i.imgur.com.

Therefore, I'd recommend updating links of the form https://imgur.com/QTk8w33.gif on your readme file by changing imgur.com to i.imgur.com so Modrinth does not force the images to be cached through a third party wsrv.nl.

In other words, for example, this is what you have on the README.md: https://github.com/CodeF53/Horse-Buff/blob/5156e1d977b7567a3e2cdf8710b2731ed72da4f7/README.md?plain=1#L19 During parsing, Modrinth changes the above line to:

![image](https://wsrv.nl/?url=https://imgur.com/JeJNEgO.gif)

I suggest changing it instead to:

![image](https://i.imgur.com/JeJNEgO.gif)

as that is what the original URL redirects to when followed in a browser.

Fixed for awhile now, but I finally pushed the changed readme to github
