Another useful bit of code for anyone interested...
You can send bmp logos/wallpapers to your device by "Send to Pocketbook" emails like you would with ebook files.
Once synced over WIFI, I run a script/application from my device to automatically move the bmp images to the correct directory.
Code:
#!/bin/sh
SendToPb="/mnt/ext1/SendToPb"
offlogo="/mnt/ext1/system/logo/offlogo"
find ${SendToPb} -name \*.bmp -exec mv {} ${offlogo} \;
I used Notepad++ to create the script above, I don't think basic Notepad will work.
In Notepad++ create a new document, then go to EDIT>EOL CONVERSION and set the value to "UNIX (LF)"
Paste the code above into Notepad++ and save/close.
Rename from .txt to .app and copy the file to you Pocketbook in the "applications" folder.
To run the script from your device just go to Applications>User's on your device and click on it. There isn't any output, but it should have moved any bmp images synced via "Send to Pocketbook" to the correct directory.
