Where to find this option in blender 2.5?

Hi
In the UV/image editing window where to find the option “consolldate into one image” in blender 2.5?
In blender 2.49b it was in image drop down menu but i can’t find it in 2.5.
Please help.

sorry , i dont know what this does, but i might know where to find it:
try hitting space.then try google. if not check the cheat sheet - (help > operator cheat sheet).

Currently on the todo list http://wiki.blender.org/index.php/Dev:2.5/Source/Development/Todo/Tools#UV_Unwrapping

Thanks Richard. Do you know when the final version of 2.5 will be available?
