how to post in this way?

[lawrencesiow]

i like the fact that blogger's template allows me to post image in this way. but i dont like their default blogskin.

anyone can decipher for me how to post the image in this beautiful 'border' so i can edit in my own blogskin?



thanks everyone

img {
  padding: 0.5em;
  border: 1px solid silver;
}

... perhaps.
