Latest Images Block

Hi Guys,

Image module also has a block, that shows the latest images,
It works fine, i.e. shows only 1 latest image.

how can i use it to show atleast 3 latest images, instead of 1, i will also appreciate it, if the blocks shows
3 latest images that are products.
i can change the php code, not sure where to change it.

thanks
Naren
