I haven't done this in sqlite, but in postgres and it was quite easy:

Saving image to database:

//Database.sch
TABLE_ (TABLE_NAME)
SERIAL_	(SOME_ID) PRIMARY_KEY
BLOB_	(COLUMN_NAME)
END_TABLE

//code
Image img;

JPGEncoder jpg(90);
try{
	SQL & SqlInsert(TABLE_NAME)
		(COLUMN_NAME, SqlBinary(jpg.SaveString(img)))
}catch...

Loading it back:

try{
	SQL & SqlSelect(COLUMN_NAME).From(TABLE_NAME).Where(......).Limit(1);
	if (SQL.Fetch()){
		Image img = StreamRaster::LoadStringAny(SQL[COLUMN_NAME]);
		//Use StaticImage to show your image on a screen
	}
}catch....
