custom image in sidebar depending on page-ID
 

Hi,
I'm not sure if this is an ATAHUALPA issue, but I couldn't find any ideas in wordpress forums.

Question:
Depending on the page ID I'd like to show an individual image in the sidebar.
PageID-78 shows image78.jpg in the sidebar. PageID-123 displays image123.jpg.

--> NextGen is no option, because it shows images by random.

Is there a HTML-code, which I could insert into a "Text Widget"?

Thank you for helping me!
Best, Vito

P.S: I'm using version 3.4.1

Problem solved with the wonderful widget "widget logic" (http://wordpress.org/tags/widget-logic).
