Do you want your own image at power up to personalise your device?
You can!
Save a 240x304 24-bit BMP file named `splash.bmp` in the root of the SD card. You can share and get ready to use images in the `#splash-screens` channel over our [Discord](https://discord.gg/tuwVMv3) group. Beginning in firmware version 1.7.4, splash screen BMP files stored on the SD card can be viewed in the File Manager application and set to be the current splash screen with a single click.
Save a **240x304 24-bit BMP file** named `splash.bmp` in the root of the SD card. Beginning in firmware version 1.7.4, the splash screen BMP files stored on the SD card can be viewed in the File Manager application and set to be the current splash screen with a single click.
### Issues
- If you're having problems (doesn't display when clicked in Fileman) with 240x304, try 240x300 instead.
- If you don't see a(custom) splash screen, make sure the feature is enabled by ticking the box in Options -> Interface -> Show Splash.

## Example
Some picture editor providing an exporter which can be configured. But to convert an existing picture, you could use [ImageMagick](imagemagick.org), which is a powerful image manipulation tool. It is open source and available for all common operating systems.
To just scale the picture down, use:
```
$ convert source.jpg -resize 240x304 destination.bmp
```
If you see and don't want a frame left and right, you can adjust the convert with:
```
$ convert source.jpg -resize 240x304 -gravity center -extent 240x304 destination.bmp
```
To check if the splash got the required parameter, check:
```
$ identify destination.bmp
destination.bmp BMP3 240x300 240x304+0+0 8-bit sRGB 216054B 0.000u 0:00.000
```
It says '8-bit', but is is for RGB -> 8+8+8 = 24-bit
## Issues
- If the custom splash is not shown in Fileman, try the size **240x300** instead of 240x304.
- If you don't see a (custom) splash screen, make sure the feature is enabled in `Options -> Interface -> Show Splash`.
