Access to the files in 'web' folder not allowed

I’m getting this, when i’m trying to show images with photoswipe library:

XMLHttpRequest cannot load https://api.backendless.com/E1E3DD63-BBE0-339D-FFF8-09F563E4EA00/v1/files/web/balkitImages/CE7E40F1-FE59-449C-FF9F-883FEAE27400-0.jpg. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:4444' is therefore not allowed access. The response had HTTP status code 404.

It’s not specific for http://localhost:4444 - i’m getting the same error on my server.
It’s works ok, when images are placed on my vps.

Hi Anton,

Please see this:

If the request goes out as CORS, make sure all the appropriate HTTP headers are present.
