Okay,

I got this far:

		cObject.stdWrap.override {
			cObject = CONTENT
			cObject {
				table = tx_myext_image
				select {
					// this pid needs to subsituted with the page root!
					pidInList = 1	
					// this needs to be dynamic
					where = product=8
					selectFields=image
				}
				
				renderObj = IMAGE
				renderObj.file {
					import.field = image
					import = uploads/tx_myext/
					width = 200c
					height = 150c
				}
				//renderObj = TEXT
				//renderObj.field = image
			}
		}

I don't understand though, why it generates an empty img tag. When I 
have it rendered as a TEXT object it displays the filename correctly. 
The file exists in the uploads folder.

Anyone?

Any ideas on how to substitute the product=8 with the current value of 
the list item (since this is part of the list item).

Thanks in advance for your thoughts...
