This is an image of a blackboard:

enter image description here

I would like to reduce its height while its width, and all its four wooden borders (top, bottom, left, right) should stay unchanged.

Could anyone kindly suggest how this can be done in Photoshop/Fireworks?

I just started learning Fireworks (sort of like a lighter, more web-oriented version of Photoshop) a few weeks ago, and I found a pretty cool feature called 9-slice scaling. Basically, you can fix this problem easier in Fireworks with 9-slice scaling. You can tell Fireworks exactly where the borders are located with 9-slice, and scaling it will only scale the parts of the image that aren't the borders.

If you need to learn more about 9-slice scaling, just Google it. And you can get a free 30-day trial of Fireworks from Adobe's website.

I got my question answered by doydot here, many many thanks to him and his answer should be useful to other people:

Each side will have to be separated in order for this to happen (including blackboard) The left and right borders need shortening by free transform and dragging by the middle not side to keep the width of the border. Do the same for the blackboard. Line everything into place.
