Signature Frame...Pic Size???

Hi ladies, I really want a signature frame at our wedding. We registered at BBB and the only signature frame I see is the one (in the link that I will include below).

You know what it is? The pic looks SOOOOOOOOO TINY on the website so thats why I'm so confused Do you think that pic would be big enough and I can put it on my registry??
