There is actually a bit of a known issue. QQuickImageProvider is the
correct way to bring custom image data to an image, but if you're
rendering a custom item which wants to use image providers you can't
currently because QQuickPixmap is private (and so you should not use
it). I'm considering making it public because it's essential for this

If you instead meant that you've gotten a URL from QML and need to
load it, in a network transparent way, what we usually do is check the
scheme for file: or qrc:. If it's either of those we load it directly
with QFile, otherwise we use the
function to get a QNetworkAccessManager which can be used to fetch
data from network sources as well as custom URLs. Except image
