Lost clipart in Word

[Dave]

Hello,

Recently I've noticed when I search for clip art under
Insert|Picture|Clipart I only seem to get a few options.
I remember there being lots more images, and these don't
seem to be found now.

For example if I search for 'dog' I get a single image of
a dog. I'm sure there used to be lots more.

Can anyone help me reset this part of word ?

Thanks
