Images don't work on subdomain

Hi guys,

I have a problem with images on subdomain. I created subdomain (m-test) for mobile version of site and use http://detectmobilebrowsers.com/ for detecting that user connecting by mobile device or desktop. The best option I think would be to use Mobile add-ons for EE3 but this add-ons is for EE2 version only. However idea is the same.

And now, for example, this one works:

https://test.testing.com/images/uploads/folder/image.jpg

but that one not:

https://m-test.testing.com/images/uploads/folder/image.jpg

. So “m-test” subdomain doesn’t have an acces to images. Do I have to set up the paths in index.php file?

Basically I want to create a mobile version of site that uses all content from main domain (all articles, images etc.). Unfortunately the domain “m-test” doesn’t have an access to main domain folders. How to solve it? Or maybe there is a better approach to create a mobile version?

And something else… When I go to “m-test” by desktop that all images are visible (they have path “test.testing.com/images/….”). Unfortunately in mobile they are not visible (probably because “detectmobilebrowsers” script changes {site_url} to “m-test” so path is wrong “m-test.testing.com/images/….”).

I use EE 3.0.4.

Thanks for your help and sorry for - I guess - trivial question!
