XML : Display Image in xslt

I have an xml file, Nodes of that XML file contain a screenshot full path

Example C:\usere\blablabla\name.bmp

I want to use this path in xslt to display my image, but in place to image small icon is displayed.

My code

<img><xsl:attribute name="src"><xsl:value-of select="Screenshot_Location"/></xsl:attribute></img>

but if i give relative path then image shows up
