Try this one example i'm still working on.
You must be talking about the qrc file (resource) and loading the png images to an object (QPushButton in the example) ... something like that?!

QPixmap Sender::selectImg(int i){
    QPixmap image;
    switch (i){
        case 0: image.load(":/quatroestacoes/primavera");
                break;
        case 1: image.load(":/quatroestacoes/verao");
                break;
        case 2: image.load(":/quatroestacoes/outono");
                break;
        case 3: image.load(":/quatroestacoes/inverno");
                break;
        case 4: image.load(":/quatroestacoes/as4estacoes");
    }
    return image;
}

QPixmap Sender::selectImg(int i){
    QPixmap image;
    switch (i){
        case 0: image.load(":/quatroestacoes/primavera");
                break;
        case 1: image.load(":/quatroestacoes/verao");
                break;
        case 2: image.load(":/quatroestacoes/outono");
                break;
        case 3: image.load(":/quatroestacoes/inverno");
                break;
        case 4: image.load(":/quatroestacoes/as4estacoes");
    }
    return image;
}

To copy to clipboard, switch view to plain text mode 

In this function i select an imagem, load it into a QPixmap object, and the return it to the call point.

You must replace ...

image.load(":/quatroestacoes/as4estacoes");

image.load(":/quatroestacoes/as4estacoes");

To copy to clipboard, switch view to plain text mode 

... by something like ...

image.load("yourpath/imagename.png");

image.load("yourpath/imagename.png");

To copy to clipboard, switch view to plain text mode 

... if you have not created the resource file.
...but there are many other ways to do it

Here is a simple one:

ui->receiverLight->setPixmap(QPixmap("imagens/off.png"));

ui->receiverLight->setPixmap(QPixmap("imagens/off.png"));

To copy to clipboard, switch view to plain text mode 

Where:

• receiverLight is a QLabel object
• the file name of the image is off.png

Dont you have access to Qt Demos ? It is a very good place to start with.
You will get almost every example you need for a beginner .
