Here 10 tips to organize your photoshop layers when you work on web sites layout:

1. Before start working, create folders to organize your layers.. Organize them in a tree format (take a look at the image). If you start without folders, you’ll loose a lot of time to re-organize layers.
2. Use forlders colors (easier to identify folders and quite prettier).
3. Name the layers: you have to name them when you create, not later. Name ALL the layers or you will mess your photoshop work.
4. Create a lower folder to organize the images sources (logos, cutted images, artworks). If you crop or modify some source, you can always get the unmodified original quite fast without looking for them in your hard-disk or on the web.
5. Link the layers that should be linked.
6. Don’t raster font layers…
7. Join layers as soon it get your work easier (sometimes It’s better to have less layers).
8. Create a top forlder called BROWSER (here you’ll put the browser frame: sometimes clients want to see the “site preview” inside a browser).
9. Don’t use layers comps if you are not sure about that (I once tryed it and lost yours or work).
10. Save final composition to PNG (gif is color number limited, JPG has fucking compress “same color” problems). PNG is quite heavy format, but is a looseless format!
