Locking layers
You can fully or partially lock layers to protect their contents. For instance, you might want to lock a layer fully when you finish with it. Another layer might have the correct transparency and styles, but you are still deciding on positioning, so you want to leave that layer partially locked. When a layer is locked, a lock icon displays to the right of the layer name. The lock icon is solid when the layer is fully locked; it is hollow when the layer is partially locked.
To lock all properties of a layer or layer set:
- Select a layer or layer set.
- Do one of the following:
- Click the Lock All
option in the Layers palette. - (ImageReady) Choose Layer Options from the Layers palette menu, and select the Lock All option.
Note: When a layer in a locked layer set has individual lock options applied to it, the lock icon is dimmed 
.
To partially lock a layer:
- Select a layer.
- Click one or more lock options in the Layers palette. (In ImageReady, you can also choose Layer Options from the Layers palette menu.) Select one or more lock options:
- Lock Transparency
to confine editing to the opaque portions of the layer. This option is equivalent to the Preserve Transparency option in earlier versions of Photoshop. - Lock Image
to prevent modification of the layer's pixels using the painting tools. - Lock Position
to prevent the layer's pixels from being moved.
Note: For type layers, Lock Transparency and Lock Image are selected by default and cannot be deselected.
To apply lock options to all linked layers or all layers in a layer set:
- Select a linked layer or a layer set.
- Choose Lock All Linked Layers or Lock All Layers in Set from the Layers menu or the Layers palette menu.
- Select lock options, and click OK.
