//edit the 5 steps below to configure...

// 1) substitute 116 and 42 with the width and height of your logo image, respectively
var logowidth=50
var logoheight=50
var logoimage=new Image(logowidth,logoheight) // do not edit this line

// 2) change the image path to reflect the path of your logo image
logoimage.src="http://www.lodbrok.be/img/ragtower-50.png"

// 3) Change url below to the target URL(s) of the logo
var logolink="http://www.lodbrok.be/"
var hiddenlink="http://wiki.lodbrok.be/"

// 4) change the alttext variable to reflect the text used for the "alt" attribute of the image tag
var alttext="logo"

// 5) Finally, below variable determines the duration the logo should be visible after loading, in seconds. If you'd like the logo to appear for 20 seconds, for example, enter 20. Entering a value of 0 causes the logo to be perpectually visible. 
var visibleduration=0

// Optional parameters
var Hoffset=5 //Enter logo's offset from right edge of window (edit only if you don't like the default offset)
var Voffset=20 //Enter logo's offset from bottom edge of window (edit only if you don't like the default offset)
