Dynamic image from url into crosstab

Dear all,

I created a crosstab in a design studio application retrieving the employees information (number, full name, ...) and the posted time by projects from SAP BW BEx Queries.

The employee pictures are available on a server reachable via an URL like http://<server_name>/<employee_number>/width/70

What I would like to do is to display the employee pictures for each employees into the crosstab using the server URL picture.

How is it possible to do it?

Thanks in advance,

Best regards,

Benjamin
