how can i add a right click menu to finder

Question

how can i add a custom view to the right click menu of every file in os x finder?

e.g. i want to display the image if it is an image type and do some custom action etc.

is this possible with c or objective-c? if yes how? (without using any available tool)

Answer 1

You need to write a Menu Manager plugin based on CFPlugin. Unfortunately, this involves some really dated Carbon stuff. There is a tutorial from a few years ago at mactech

Note that this stuff may be obsolete with Snow Leopard, though whatever they come up with is probably going to be much easier to deal with than Menu Manager/CFPlugin cruft.
