relative path to external resource

[SyntaX]

Hi there :D

I am playing around with Qt for WebAssembly and was wondering, how to use assets from a relative path from the compiled warm if deployed on a server?

Assuming I use some images in my application, I would normally embed them in my qrc resource file,
but for WA the compiled binary is already really large, so I thought I could load the images directly from the hosting server, is this possible?

Image {
    //source: "../../assets/BG.jpg" // local, using embedded resource from arc file
    //source: "file:///assets/BG.jpg" // local, absolute path -> works for desktop build
    //source: "http://my.server.com/BG.jpg" // online absolute path -> works for WA build, although I have to pay respect to the protocol (http or https), also difficult because of CORS if deployed on another server
    source: "file:/BG.jpg" // online relative path how to?
}

trying to load an image from a relative path throws me an error:

QML Image: Cannot open: file:///BG.jpg

Do I have to map my relative path to an absolute like in this post: https://forum.qt.io/topic/76590/relative-path-to-absolute-path or is there another way to achieve this?

best regards

@SyntaX You would need to preload the files at compile time.
