Can't load Image source in QML Image

This seems really basic but for some reason I can't get the image source to work in the ultra-simple QML app below.

FYI, I'm running Mac OS-X 10.9.5, Qt Creator 3.2.1 based on Qt 5.3.2. 

import QtQuick 2.3
import QtQuick.Controls 1.2

ApplicationWindow {
    visible: true
    width: 640
    height: 480
    title: qsTr("Test")

    Image {
        id: image1
        x: 10
        y: 10
        width: 100
        height: 100
        source: "testImage.png"
    }
}

I get the following error:

qrc:/main.qml:10:5: QML Image: Cannot open: qrc:/testImage.png

The application window is created but no image is displayed. I've also tried wrapping the image within a Rectangle but this doesn't help.

What am I doing wrong here?

The "testImage.png" is in the project directory and I've tried all sorts of ways to specify the image path using resources, absolute, relative, and even specifying the image source manually with the QML UI designer.

I'll also mention that to get Qt 5.3.2 to work I followed the modification suggested HERE.

Thanks.

doc.qt.io/qt-5/qml-qtquick-image.html#source-prop The URL may be absolute, or relative to the URL of the component. qrc URLs are relative. You can also use file:///home/user/testImage.png , or you can define your own QQuickImageProvider that can handle your own scheme, e.g. Image { source: "image://myimageprovider/testImage.png" } - Alex Bitek

I suppose that your qml file is in resources, so try place your testImage.png image in resources too. Recompile app, run it and check is image works properly.

All should be together. For example:

enter image description here

My code:

Image
{
    source: "images/earth.png"

If I delete this image from resources, I'll get this error too, but image still in the correct place in file system.

When qml source placed in the resource, then all files, which loads from qml should be in resource too (Qt searchs this files in the resources, not in the file system).

If you are locating from local filesystem , get the file path and prefix "file:" as source = "file:/root/Desktop/Rathod.png"

I had a similiar problem and solved it the following way:

  1. Right click on your qml.qrc, then choose "open with" -> "Resource Editor"
  2. Once you are in the Resource Editor click on "Add missing file", there choose your image
  3. Lastly open your qml file in the Design editor and click on the Image element, on the right side choose the path to the image

There can be two problems:

  1. The image is corrupt, although the image was correctly displayed in all previews IconImage refuses to load it. Try to use another image that is known as work correctly It seems that the Qt Image loader is very sensitive to the image format.
  2. There is a resource cache problem. Try to delete qml_qmlcachea.qrc in your compiling folder and try it again

If you are using qrc, make sure the image is added to your project. Just having it in your source directory may not be enough. For example, my main.qml is located in a particular directory. I move my .png into the same directory. I then "Add Existing Files.." and add the .png to the project. My image has the following

source:"qrc:<same dir as main.qml>/image.png"

Try to close Shadow Build under Projects->Build Settings.
