      @ManiRon How do you actually print? Also, you're using a relative path to the image in your HTML, depending on the current directory at runtime it will or will not be found.

        @jsulm I have defined path also but the image is not displaying , whether we cannot display a image in a file using QFile concept?

          @ManiRon I still don't understand what exactly you're doing: first you say you want to print, now you say you want to display. Can you explain what exactly you're trying to do?
          An image file is not directly part of a HTML document. A HTML document can reference images, but these images are stored in files, not in a HTML document. So, I don't know what you expect to see.

              @ManiRon
              Like @jsulm I am still at a loss about what you are asking. I don't know what your code is about either, it opens files (for read/write at that), then doesn't use them....

              All you can do is if your HTML contains

              <img src="Logo1.png" alt="Test" >
              

              then there needs to be a file named Logo1.png in the directory where that HTML is executed from. How it gets there is irrelevant: it might be something already there, you might create it from code, I don't know, but that's what you need. QFile is not needed, and cannot somehow be "passed" to HTML.

                @JonB said in how to insert an image in a QFile generated file using HTML:

                <img src="Logo1.png" alt="Test" >

                could you please give an example for printing the image using html in a html file using QFile concept in QT

                  @ManiRon If you don't explain how you're showing or printing your report nobody will be able to help you...
                  Is this "printing" you mean

                  qData << qTextRep.document()->toHtml();
                  

                  ?
                  To display this report you can simply open the HTML document in a web browser (the picture must be in the same directory as the HTML document!). Or show it in Qt Web Engine.

                      @ManiRon The code you posted does not print anything (except HTML text to the console), so I'm not sure what your question currently is...
                      Just to be sure: by "printing" you mean print on a printer?

                                    @ManiRon said in how to insert an image in a QFile generated file using HTML:

                                    Is it in the same directory as the HTML file? No

                                    Well, then I would say this is the problem (and I already said that before: "the picture must be in the same directory as the HTML document!").

                                      @ManiRon I asked 3 questions. To which question does "yes" belong?

                                          @ManiRon "i have to place my image at place where i am saving my html file" - yes!
                                          How can web browser know where the picture is if the only information you give it is the file name without path:

                                          <img src="Logo1.png" alt="Test" >
                                          

                                          ?! So, where should web browser look for this picture?
                                          "But if i give the path its not accepting at all" - how do you give it the path? Please show...
