Photoshop resize tool

[Haskell304]

Hi, Ive been playing with photoshop for a while now off and on. For some reason with the new version (CS3) I cant find a tool to resize an object in an image. Im not trying to resize the whole image, but just an object. Does anyone know if im just overlooking it and can tell me how i can utulize this tool. Or, is it not in this version?

If I understand your question correctly, go to Edit, and press Free Transform while the object is selected. That will allow you resize a particular layer object.
