    Image preparation

    Firstly, you need to prepare a picture/photo in the format of 296×128 pixels. We can easily find a photo resizing tool online, for example, the Online Image Resizer.

    Following the instructions on the website, then download the generated image in JPG format.

    Secondly, we use the Image2LCD tool to transfer the downloaded 296×128 image into hexadecimal codes. You can visit this YouTube link to get detailed instructions.
