By default psd2css Online makes all the layers and images named 'Layer-1', 'Layer-2', 'Layer-3'... But if you want to create separate PSD files to use as reusable components accross a number of web pages, you run into naming collisions - you can only have one Layer-1 DIV in your web page for example.
That's why we've added the '_basename' Layer Naming Convention. You can name one layer in your PSD file 'something_basename' and instead of 'Layer-1' and 'Layer-2', etc. psd2css Online will generate 'something-1' and 'something-2' layers and something-1.png and something-2.png, etc.
Here are the files from the video tutorial:
