The function bigImg() is triggered when the user moves the mouse pointer over the image. This function enlarges the image.
The function normalImg() is triggered when the mouse pointer is moved out of the image. That function changes the height and width of the image back to normal.
The code when put into an HTML Box doesn't work (at least for me it doesn't).
I get the error: 'folding element body into parent' on the firet line of the code
The same code when put into a gadget works.
