# examples/ili9341/slideshow
![](./slideshow.jpg)
This example uses the image package for TinyGo to display png and jpeg images.
## How to create an image
The following program will output an image binary like the one in [images.go](./images.go).
```
go run ./examples/ili9341/slideshow/convert2bin ./path/to/png_or_jpg.png
```
## Notes
Displaying a 320x240 png or jpeg often requires more than 50KB of memory.
The examples include samd21 settings, but if you run them as is, you will get a memory size error.
