Here are some recent examples of work I have done for customers just like you. The pictures are arranged with a before shot of an area on the left and the after shot of the same area just to the right of that image. If you place your mouse pointer over a picture you will see that the pointer changes to a magnifying glass with a small plus sign. If you click the picture once it will expand so you can see more detail. Clicking the expanded picture will return it to it’s original size and allow you to view other pictures.
You may also view the pictures as slide show by clicking the [Show as slideshow] link above the pictures.
