How to assign an image url dynamically?

Im trying to present a group of products on a order page and to this end i also need to display a small image of each product. The data is presented on the page using Netui:callcontrol to retrieve the data from the database control. The images are saved on the webserver and i was planning to merely link to them.

Now i was thinking i could retrieve the image url like all the other data by referring to the element in the itemcontainer. for example...

<netui:image src="{container.item.img}"/>

However this is not possible..

Is there anyone with an idea of how to achieve this? or perhaps another solution to this problem?

Hi,

Why do you say that it's not possible tu use something like this : <netui:image src="{container.item.img}"/>
?

because it won't assign the value of the container item to the image source. The result of trying to use " <netui:image src="{container.item.img}"/>" is an image that is not availiable. The url for the image in the browser is as follows...

http://localhost:7001/resources/images/{container.item.link}

so it is not possible to assign values to an image dynamically.
