Add Picture in Crosstab with URL

Dear all

Is it possible to add a Picture to a Crosstab with a URL Access, relating to a Value in the Crosstab?

For example:

Crosstab incl. Material Nr.

Material Nr.                          Picture

123456                                  Picture of the Material Nr. coming from a URL http://imageserver.com/Material-Nr. 123456

Can I add a Column as in Webi wtih this concatnated String of URL and Material-Nr.

If yes, how can I do that.

How to steps I really appreciate.

Thank you.
