Now, open menu.cpp. Find the MainMenu function. To load an image, you declare an instance of the GuiImage class. Unless, in the main window, you will want to declare it this way:

What is the ImageData inside the initializer function? Well before actually creating the image, you must load your image. This can be done by creating an instance of the GuiImageData class:

The image source is your image buffer, where the contents of the image are help. The image must be in the png format, and have dimensions that are a multiple of 4. To load an image from an sd card to an image buffer, do the following:

You may be wondering how an image gets loaded into a buffer. Whenever you want to add a new image, you must copy the image to the source/images folder, and add it to filelist.h:

Then your image will be put into the ''image_name_without_.png''_png buffer when it is compiled.
