I am new to web design and have created buttons in Photoshop, but would like to know if the button layers have to be merged before you can optimise and slice them.?
Just in case I have to come back and alter them.
I have a button with three layers in Photoshop CS I selected Group from Layers and named the group Button1.
When I go to Layers>New Layer based Slice its greyed out.
I cannot create a slice, the only way I seem to be able to do so is the Merge the layers.
