I just switched from using PSP to Photoshop, and I'm still learning the basics on it, so how do I add a simple 1px. black border around an image, like you can in PSP. All I had to do in PSP is go to Add Border, but Photoshop doesn't seem to have this feature.

Hi!

Select the color you want to use and click on Select->Select all.
Then go to Edit->Stroke...
Enter the bordersize in pixels and click OK.
That should do :)

Thanks. I was so confused about that, and all my stuff looked really bad and un-finished because of the lack of borders.

Your welcome :)

You can also merge layers and double click your layer, and go to stroke. I find I use that more.
