Comments on Instagram pages

I used the fact that the {PostID} variable is empty for static pages.

So declare a CSS class like this:

.hiddenOnStaticPages {
    display: none;
}

Then wrap the comments link (and the actual comments) in a div like this:

<div class="hiddenOnStaticPages{PostID}">
Comment HTML goes here...
</div>

UPDATE 06/11/2012: This is now possible “natively” by going to instagram.com/profile_name. Source.

UPDATE 17/04/2020: But clicking any picture opens a login popup instead of details

Yes, if you know your friend’s Instagram username, you can use Webstagram. Search for his/her username and see his/her photo stream. (E.g.: Ariana Grande’s photos.) However, note that if the respective user’s profile is set to private, you can’t see the photos. Source.
