Perspective Crop with Adobe Photoshop CS2
This is a great tool, my lesson here is something I learned from a quick time video that a fellow photographer sent to me.
First let's let you see the before and after results so you can see if this is something you will be interested in using.

Above is the original taken by my friend Bob Thickman in the Dallas Texas area, and you can see that the table is level, but the background used has some lines that do not look level or square. Using perspective crop tool, you can get everything square very easily.
As you can see below.

Here is how it's done.
1.
Load your image into Adobe Photoshop, I used CS2, but I would guess that PSCS for sure has this also, but perhaps even 7 does too.
Click to use the Crop Tool, or depress C which is the short cut. Draw a crop over the image over the area that you wish to mark for correction, see the example below. Make sure to clear all the parameters of the crop, by clicking "clear". And make sure you click the little box marked "perspective", however that box does not appear until you draw the first crop over the image.
2.
Place the crop cursor now over each corner, and drag and pull each corner to a point that makes up the lines that need too be squared up with the lines that are making the image not look level. leaving the lines that already look level, look level.
3.
Now pull each of the side points out to the edge of the full image so to allow as much of your image to be included as possible.
At this point you double click or press Enter to make the transformation take place.
Your final step is to use the crop tool one more time, to crop off the areas that are left blank due to the transformation to make the perspective crop, and your done.
I am sure you will find good use of this tool.
