A quick note of thanks to Eric Wang, who took my PopUpImage NSButton subclass and reimplemented it as as 
NSPopUpButton subclass. Aside from benefiting from NSPopUpButton's menu-related methods, Eric's implementation 
makes use of an NSPopUpButtonCell subclass, so you can use the control in a table or matrix too. So, cheers to Eric!



Both versions of the control are available for download from my <a href="http://mattgemmell.com/products/source/">Cocoa source code page</a>.
