I know why this is as it happened to me the first time I've worked on re-sizing the elements to fit my page or to flip it around to make it face the other way.
So as not to lose the original dimensions of an element, I am sharing with you what I do. There may be other better ways I've yet to discover but this works for me and I'll keep doing it until I discover a short cut or better way to do it.
I used CS3 extended in creating the pictures below, you will be able to do it with any photoshop versions as the process is still the same.
Open the element you want to use. If the element is already on your digital layout, choose that layer.

Under EDIT, choose FREE TRANSFORM. Your screen or layer should look like the one below. You should be able to see a "box" of lines surrounding your element. There are "handles" at each corner, top and bottom, right and left sides of the box.
To re-size the element, grab one of the corner handles. The cursor should change into a double-ended straight arrow. Press the SHIFT and ALT keys while you move the cursor inwards [making the element smaller] or outwards [making the element bigger].

So there you are. Don't forgot to press SHIFT + ALT when re-sizing to keep the dimensions intact.
If this were a flower and you'd want to use five of the same flower, and of different sizes, don't forget to turn them around a little bit in different directions so that it will appear that you have different flowers instead of one - this is especially true if one petal is folded or shaped differently than the others. If you transform the flower and move it around so that particular petal is on the right side or at the bottom, then the flowers will not look alike.
To rotate the element, choose EDIT and FREE TRANSFORM once again. Bring the cursor outside the "box" in one of the corner handles. The cursor will change into a double-ended curved arrow. Now move the cursor up or down. You may want to hold down SHIFT + ALT just in case so you won't make a mistake of re-sizing the object.
Next lesson will be about re-coloring an element.
