datagrid with images

[Arda]

Firstly hi to all,

I have collected countries short names into SQL Country column.(e.g.
US-United Sates, RO-Romania,TR-Turkey).
I want to combine them with the country's flag picture.(e.g.
US.jpg,RO.jpb,TR.jpg)
I mean I want to make a datagrid which shows the Country column with the
flag pictures that have the sama names in SQL.

1.How can I do this?
2.Is there anyone or anywhere that I can found all countries flag icons?

Any help will be appriciated
