As you saw before, slicing is fast and easy. It also divides the image perfectly, with Photoshop doing all the math necessary to split the image in as many cells or tiles as you want. We used the "Inside" method of stroking -- but it cut off parts of the image. In order to use the 'outside' method, the slice function won't work. We'll have to cut them out manually.
Not being particularly fond of math, I usually divide images using this little trick. It won't take but a minute.
Draw a square shape into a new layer. Here I drew one, filled it, and then set the opacity for about 80% so I could still see my image. I used the Move tool to Option/drag (Alt/drag) the second, and third squares. Then I did the same to drag copies of each row until I created a grid of nine squares.
Now, I will carefully select each tile, using this grid, but select outside the image rectangle to compensate for the width taken by the "Stroke Inside" layer style. This gets a little tedious.
Upon making the selection using the Marquee tool, I click the original image, and float a copy of that selection to its own layer. Float by hitting Command/J (Control/J). The tile on its new layer will be de-selected, so Command click its thumbnail in the layers palette, return to the original image, and still using the Marquee tool, move the selection alone (without image) to select the next tile.
After moving the selection rectangle to the next position, again, return to the original image layer and float a copy of that selection to its own layer. Walk your way through the file until you've picked up all nine tiles. If you view them all at the same time, you should see a seamless copy of the original image.
Once you have all nine tiles lifted to their own layers, you can turn of the view of the original, set layer styles and duplicate styles as described in the previous section.
This adds another 20 minutes or so to the time, but in my opinion, makes the finished piece better. The images look as if they would match up.
Now, if you don't mind rounded corners on your images, you can use the Slice method, and simply set the Stroke style to the outside rather than inside...
Above, you can see the impact of rounded corners. If these are okay, then use the slice method and set the Stroke style to the outside. Notice here, I've also played with the layout a bit, slanting or tilting the images to give the presentation a more casual look. I think the rounded corners add to that as well. At this point, you know the technique -- it's just your call as to how to apply the stroke.Click to see an enlargement.
Now, let's make a different mosaic...

from the Editor:
I was delighted that day back in 1989 when Peggy Killburn called to ask if I could handle one more speaker in my "Great Graphics Tips & Tricks" session scheduled for the 1990 Macworld Expo. "Yes" was my response to her request to add Russell Brown to my panel. After all, we loved Adobe's young "Illustrator" program, and were quite anxious to try out their upcoming new product called "Photoshop." After seeing his demo, I was convinced Photoshop would be big. So the next month we added "Photoshop Tips & Tricks" to our regular DTG Magazine uploads to Compuserve, GEnie and AOL. The rest is history.
I only regret that I didn't trademark the name.
