You can view and copy the code for using google translate (as in my post footers) from here. (Placed it in an external link coz people started telling me that some thing is broken in my blog and code is spilling out!)
The image based goolge translate code contains direct links to the images of flags of the respective countries. You may use the same links or modify and upload the images to your server or image host and replace [image source] with the direct URL. Or use text links like me. The code for the text links is also located in the link. Incase of any problems, feel free to drop a line here. adios!
