      @mfs12 I can successfully change the splash screen with the bmp2C tool. Here are some photos to illustrate my problem:
      First, the splash screen (this one is just a random image for the example) :SplashScreenCNC.jpg

      And now, the same image displayed with the StaticImageField() function, after following the procedure described in my previous message:ImageCNCFailure.jpg
      (The screen may look unfamiliar, as I have already customized and removed some buttons 🙂 )

      So, I think my array is good, but I may miss something when calling the StaticImageField()...

      Here is how I call this function: mgr.AddField(new StaticImageField(row3, DISPLAY_X - 270, 120, 131, ImageCNC)); //height = 120, width = 131

      And my ImageCNC array is: extern const uint16_t ImageCNC[] = { 131, 120, 0x0292, 0xffff, 0x0000, 0xef5d, 0x0000, 0xd69a, 0x0071, 0xd6ba, 0x0000, 0xe6fb, 0x000d, 0xffff, 0x0000, 0x7bef, 0x0072, 0x0000, 0x0000, 0x39e7, etc. }

        @Nil-Orbach sorry, my ressources are limited i can't assist you on that. But hope you will succeed.

        It really looks like the mapping is not yet correct. Does the image fit the dimensions you want to draw? I would expect they need to be accurate.

          @mfs12 I keep looking for what may be wrong. I hope I succeed too so that it will help those who could face the same problem in the future 🙂

          The image dimensions are good. Here is the same image displayed as a button, with the AddIconButton() function and an uint8_t array of my image generated with the bmp2c tool thanks to your first message:
          ButtonCNCSuccess.jpg
          The button is large, but the image dimensions are the same than those displayed with the StaticImageField() function.

          Anyway, thanks for your help, that was very kind! 🙂

              @mfs12 Hi, actually it was not really solved, but as nobody seems to know the answer, I guess you can close it 🙂

                @Nil-Orbach check the drawing function of the button. Finally it should be the same as for images.

                  @mfs12 these functions are not exactly the same. The button function calls drawBitmap4() which then calls LCD_Write_Repeated_DATA16() whereas image function calls drawCompressedBitmap() which then calls LCD_Write_DATA16(). These functions may look similar, but I do not think I will explore that further. I will let my image as a button, it is not that bad!

                    @Nil-Orbach so this seems to be your problem then. Your image does not have the right format.

                    And which function does the splash screen use?

                      @mfs12 According to what dc42 said, my image has the right format. dc42 said:
                      "The format is very simple:

                      • word (16 bits) repeat count minus one (so 0 means that the following pixel is displayed just once, 1 means it is displayed twice etc.)

                      • word (16 bits) pixel colours in 565 format (e.g. 5 bits red, 6 bits green, 5 bits blue)

                      • Repeated as necessary"

                      This is exactly what I got after using the bmp2c -binary command, and after opening this binary file with a binary editor and copying the uint16_t hex code into my code so that the StaticImageField() method can display it by calling drawCompressedBitmap().

                      Here is the splash screen format:
                      15f5d172-dbe6-4320-a777-d681131a6647-image.png

                      And here is my image format in the code:
                      6aebcf94-a47a-4e22-a0a7-856d2b7b4e43-image.png
                      They are the same!

                      Concerning the splash screen, it is called with drawCompressedBitmapBottomToTop(0, 0, DISPLAY_X, DISPLAY_Y, _esplash + 2).
