i was browsing the code and discovered references to a picture file. i am wondering if this is for sending an android app icon, or if it is for sending attached images from notifications (like in messenger apps).

i can't seem to get it to work either way, and some messenger apps don't even seem to send notifications at all.

some testing i did with different apps:

signal/molly/signal-foss: no notifications at all
discord: text only; will show image attachments as text names (image.png)
aosp messenger (default android sms): text only (if a message is mms it will not be shown by the server)
a2ln test notification: uses the default "info" icon on linux notify-send

picture_file stores the content of [getLargeIcon](https://developer.android.com/reference/android/app/Notification#getLargeIcon()), which may for example be a profile picture in WhatsApp. I also noticed that sometimes there is no picture when there should be but I didn't bother taking a look at it because it seems to be intended (by Android). If there is no icon (getLargeIcon returns null), the server sets dialog-information as the icon whose exact look is desktop dependent.
