Oh my God....

Let's see... you are loading an image and placing its url into an html document, then setting that html on a text edit with a method returning void and wanting the result of this method to be written to a socket (look in the dictionary what the word "void" means in English) and expecting the contents to be transfered to the other end of the socket... Please tell me I'm wrong...

Definitely not a method returning void. And, frankly, surely a good book about C++ and programming in general. Then also a bit of RTFM and STFW.

Or better, how can i put that image in the QTextEdit using the socket?

A good first step would be to browse the reference manual.

Then act as a beginner and learn the basics first before moving forward to more advanced subjects. If you don't even know what a return type of a method does how do you expect to make progress with using the API?

I still don't know what you want to do so it is quite hard to help you. If you want to transfer this html through the socket then use QTcpSocket::write() as already told. Finding the proper transformation from the type returned by QTextEdit::html() to the type accepted by QTcpSocket::write() is your homework. It should take you no more than 20 seconds to find the appropriate method provided you start looking for it.
