apply border on image in a class.

[octoberfly]

my blog is http://octoberflyhasno wings.tabulas.c om

I tried
img{border: 10px #aeaeae}

then ALL the images in the blog have border around it. including the usericons.

I only want the image in the entries to be wrapped.
so the class is entry. but i have no control over the image posted in every entries.

<div class="entry">
<!--ENTRY['DATA']-->
<!--ENTRY['ATTACH']-->

I don't even know what code to start with.

I tried starting with
.entry{...
and I can't specify the image inside to be bordered around. If I do so, the whole box would be bordered.
So can anyone please help? I'm really sorry if it's a simple problem.

p/s: I never learn css before. I only read them from w3schools.com

In your main CSS page, do:
.entry img{border..... .}
