If you want a 1 px border, just double click the bg layer be sure you can see it..... then double click the bg layer. you'll see the blending options... go to stroke.... then add a 1 or 2 px border in the color you want inside or outside. then go look how it looks when you save it... (BACKUP YOUR .PSD) go find the result you like and your done
Good luck, oldie :happy:
