I faced the same problem . It was because i had already moved the png file in my projects folder. But i tried to add image by clicking add new where i should have clicked add existing.

This Warning is about PNG formats and Qt, Irrelevant to @ztono code. Read more about PNG (Portable Network Graphics) https://en.wikipedia.org/wiki/Portable_Network_Graphics

PNG has many Formats some old, some not standard for Qt. see more History_and_development You need to use Standard format in Qt.

You can convert your image to PNG Standard with Software.

OR

You can use QImage in Qt to convert your PNG pictures.

QImage *image = new QImage();
image->load("E:/Qt/TestProject/Images/connect.png");
image->save("E:/Qt/TestProject/Images/connect2.png");

Use new converted png and you will not see the warning.
