how does a link in bsp-html-file work without servername ?

hi there,

i made a small bsp-application with a html-file which includes the following.

***img src="xxxxx405.company.com:50000/irj/go/km/docs/documents/public%20documents/z_dokumente/weiss.jpg

this jpg-pic is displayed on the side.

BUT: i have to transport the bsp-appl. from test enviroment to production. and xxxxxx405 is our test-server. xxxxx404 is production, with another port.

how can i link this object without coding of the server ?

reg, Martin
