Error with Cloudfront

[Bart1909]

Hey,

I'm trying to use the plugin with AWS Cloudfront. I've set up the Cloudfront Distribution and did all settings in the plugin itself.

For those images, which have already a thumbnail, it seems to work fine. But for those images, which do not have a thumbnail yet, I got an CORS error when calling the url like: https://abcdefgh.cloudfront.net/i.php?/galleries/Test/test-me.jpg&ajaxload=true The error message is:

Failed to load https://abcdefgh.cloudfront.net/i.php?/galleries/Test/test-cu_e260x180.jpg&ajaxload=true: No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'https://abcdefgh.cloudfront.net' is therefore not allowed access.

When I enter the url in my browser manually, it returns a json-Object with an url. The url looks like https://abcdefgh.cloudfront.net/_data/i/galleries/Test/test-me.jpg When the image is already generated, it is working fine and loads the images from the cloudfront.

Am I missing any settings or something else?

Same problem here. Any workarounds?

I've edited the main.inc.php from the plugin, that links, which start with i.php? are not redirected to cloudfront.

my main.inc.php looks so:

CORS error should be manage directly via the webserver. https://developer.mozilla.org/en-US/docs/Web/HTTP/CORS Any CDN should forward those headers by defaults
