Here's how to work on dds files in Photoshop Elements 5.0 (I just figured it out by trial and error):
First you'll need the dds plug-in package from
here
Install that into your Adobe\Photoshop Elements 5.0 folder.
Once you've done that you'll be able to edit dds files in Photoshop.
Now, to save a file with its alpha channel intact you'll want to do the following:
Open the file in Photoshop and edit it as normal. After editing, click on the 'Select' tab and 'load selection' (in Photoshop alpha channels are called 'selections'. This will load the alpha channel. Now click on the 'Select' tab again and 'Save selection'. Select 'Alpha 1' in the 'selection' window and select 'Intersect with selection' in the 'operation' window, then click okay.
Now you can save the file by using 'Save as'. A window will pop up and you need to choose DXT5 (interpolated alpha) in the drop-down list. Then save and that's it. The file should be the same size as the original. If the file is half the size of the original it means the alpha channel is not saved.
There may be an easier way to do it, but this worked for me when I altered the moon graphic.
