merging layers without a background
I want to merge 3 layers, (a logo and 2 bits of text) into a single layer. I'm working with a white background layer to make things easier. If I have all the layers visible I can select merge visable from the menu, but if I turn off the background (which is what I want) the merge visble option dissapears from the menu. How can I merge my 3 layers so that I have a see through background (effectivly a png)
