    I tested all three options.
    The first mode faced errors.
    The second one and third one showed nothing although had no issues!
    What is the problem please?

    In all cases you user the same path c:/xxxx, so i think paths are the issue.

      All images are in the same folder on my Desktop, in this address:
      C:\Users\Abbasi\Desktop\images

      So how should I give the paths of images to the code please?

        Hi
        I would move the images to an image folder under the project.
        Then i would use a qres file and the ":/" syntax
        (like here engine.load(QUrl(QLatin1String("qrc:/main.qml")));)

        https://www.youtube.com/watch?v=sWIQIi4lg58
        http://www.bogotobogo.com/Qt/Qt5_Resource_Files.php

        You can right click an image when inside the qres file and get path there.

          Hi,

          The purpose is to add a folder (or some files) to the project as resources to use them easier, yeah? OK, I did these:

          According to the tuts, I created a Resource file named MyRes like this.
          Please note that the Path there is the same path as the project (Main).

          I use /MyFiles as the Prefix and add all 4 files, the images (from the image folder on the Desktop).
          When adding the files, this message is appeared for all four files. I don't know what to do here.

            Hi
            Can you right click myres.qrc and choose "Add existing files" , then
            select the images. ?

                That is why i wanted you to move the images to under the project.
                The :/Myfile path is not correct. the files are not there...

                Anyway, now right click each image and you can copy correct path to use.

                  The program runs without error but show nothing! Does it work for you please?
                  What is the problem of this part if it's correct?

                  You say that you would move the images to an image folder under the project. But how? If you mean using those two tuts, I tried and also posted the error I faced at that time. The current style of adding the path of images (as shown in the screenshot) is rather ugly I think moving the images into a folder under the project would be nicer and better.

                    Just use the normal explorer to move the files under the project
                    Try to use the qrc:/ syntax then. Since its compiled into the
                    .exe i assumed :/ would work.

                      What is this please?

                      This time I tried the following but no success again.

                      I copied the images folder into the project folder and used an images.qrc file like this and ran the app using that prefix name. It says it cannot open the files! What is the problem this time?
                      Where did I go wrong?

                        Tried again using a new project named Main3 as below, copying the image folder into the project folder.
                        Here is the content of the files:
                        main3.pro
                        main.cpp
                        images.qrc
                        main.qml
                        page1.qml
                        Page1Form.ui.qml
                        qtquickcontrols2.conf

                        The program runs:
                        Issues window shows nothing.
                        Application Output shows this:
                        Starting C:\Users\Abbasi\Documents\QML\Main3\Main3\build-Main3-Desktop_Qt_5_9_0_MinGW_32bit-Debug\debug\Main3.exe...
                        QML debugging is enabled. Only use this in a safe environment.

                        Compile Output shows:
                        12:35:55: Elapsed time: 00:00.

                        And General Messages shows nothing.

                        The app shows nothing as the output.
                        What is the problem? Why can't I run this example successfully?
                        Why everything with Qt is that complicated and confusing?

                          You are still having issues with the paths/syntax
                          The path you use is invalid
                          Should have the form
                          qrc:/images/filename.png

                          Use the right click menu to make sure its correct.

                                  I made a default QML projected
                                  added image folder in project folder and used

                                  and it loaded image.

                                  So what ever goes wrong in your project, its minor.

                                    Is it different from the "Qt Quick Console 2 Application" project? You yourself told me to create such a project above.

                                    added image folder in project folder and used
                                    Image {
                                    id: root
                                    source: "qrc:/images/test.png"
                                    }

                                    and it loaded image.

                                    So what ever goes wrong in your project, its minor.

                                    Do you do the works just like me? And do your files contain the same thing as mine? And yours works well?!
                                    I tried the example using three projects, Main, Main2 and Main3. None gave me the expected result.
