How can I change the image of the panel?

I would like to change the image of the "Start a new request" panel that is currently displayed on the OneIM WebPortal start page.

I checked WebDesigner, and it seems that this panel uses "QBM_Common_Tile" module, and the image is controlled by the value of its property "Image()", a Function signature.

Currently, the value of Image() is "Shop" and the image of the panel is shoppingcart.

How can I change the image to a magnifying glass image?(So that you know it's a search panel.)

I assume believe there are several properties other than "Shop" that specify images, but I would like to know where they refer to.

I am not familiar with WebDesigner and would appreciate a detailed explanation.

Thank you.
