Store item images in database or on device?

Hey there,

I have some questions when it comes to store "images" / "icons". Imagine we have an online multiplayer game on android. And we got 1000 items w$$anonymous$$ch all have an icon. The items are stored in mySQL.

And now here is my question: Where do I store the icons for the items ?? Do I store them in mySQL ? Do I store them on the device ? What is the most !secure! and common way to do that?

I hope you understand the issue and have some good ideas dealing with that.
