You can now embed Instagram photos directly into your posts. This should make things easier for those of you currently posting from iPhone/Android, since imgur can apparently be a pain (I've never used it, but it's what I'm told). Post a photo to Instagram and copy the URL to your clipboard (both the standard URL or the "sharing" URL will work). To embed it into your post, click the media embed button (shown below), paste the URL into the pop-up, and click Embed. That's it!
