Slice tool help??

IS there a way to slice a part of an image with out it slicing up the whole freakin image?

You can, (in imageready) delete unneeded slices.

Delete slices and and imageready fills that area with a "fake" slice that wont save when you are done....it will be an empty table cell.
Say you have tons of little tiny slices and wanted to make them one bigger slice.
Simply, delete the ones you dont want and resize other slices manually to take the place of the deleted slices

you can also under the slice menu promote a "fake" slice to a "user" slice making it a slice that WILL save when you save all the slices
