With QTextEdit you will have to use QTextDocument::addResource():

textEdit->document()->addResource(QTextDocument::ImageResource, QUrl("url-used-in-html"), QImage("image.png"));
Just notice that QTextBrowser is capable of loading resources from local files out of the box.

not only with the QTextEdit, but there are other classes like QImage,QImageReader how can i use these classes to display the image. I have written something like this

"QString filename = QFileDialog::getOpenFileName(this);"

with this file "filename" can i display the image using QImage class (since it has fun'
QImage::QImage ( const QString & fileName, const char * format = 0 ) )

any suggess' plz welcome

If you just want to display an image, you can use QLabel. Also use QPixmap instead of QImage.
