Hi,

I'll keep it short: What is the recommended way to store an image in a KConfig 
key? I've already found ways, such as:

QBuffer buffer;
image.save(&buffer, "PNG");
configGroup.writeEntry("Thumbnail", buffer.data());
...
QImage image;
image.loadFromData(configGroup.readEntry("Thumbnail", QByteArray()));

But this stuff is quite ugly and might have some shortcomings which I do not 
see yet. As this is already the second time I need to do such operations (I'm 
regularly using KConfig as a file format because it behaves very well in 
conjunction with QVariants), I'm wondering whether functionality to save 
images could be inserted into KConfig.

Greetings
Stefan
