I am not sure about the header for the .h file.

My image is the same size as the display (320×240). What tool are you using to convert it into 16 bit? And what are the proper headers for the .h file? Thanks

I ran into this problem and used Irfanview to do the resizing.

Hi.
Maybe you need to rotate your display. It may be internally rotated.
Regards,

I have some and my image shows but it is only 1/4 of it yet my pizxel width and height are correct in the code.

If you use your own image, you need to enter it’s width and height into the image.h file. You also need to scale the image to fit on the screen. I use Irfanview for this sort of thing – you can scale as well as get the image information.
You might also mention using lv_obj_align() to put the image somewhere other than in the center…

this gave me so much trouble when I tried to use the Wifi connection , and it apparently is a known issue
I use a ESP32 development board where the GPIO 2 is connected to the led used by WiFi
it gave me lots of false readings on the touchscreen readings and freeze the TFT display and even got a BSOD on my PC fi I left it run like that a bit longer .
