No place to choose image for Joomla 1.5

Is there another module or plugin that I need for mooCoverFow_CK to work in Joomla 1.5? I downloaded and installed the 1.5 module and the Mediabox_CK plugin and the mtupgrade plugin and I don't see anywhere to assign an image for the menu items. What am I missing?

hi
the images are selected in the menu manager,edit an item and look at the params on the right

Thank you for the quick reply.

On the right, I have parameters (basic), parameters(component) and parameters (system). I don't see an opportunity to choose an image under any of them. Am I blind? Or maybe something didn't install properly? I made sure the Mediabox_CK plugin and the mtupgrade plugin were enabled.

this is the native joomla behavior, not related to any extension.
Look in the tab System Parameters...

Thank you. I was indeed blind.
