This tutorial is pretty useful on the comments section. You won't regret it! :)
1. Copy this code: <script src='http://hosting.gmodules.com/ig/gadgets/file/105066904960012479556/nccode.js' type='text/javascript'/>
<script src='http://hosting.gmodules.com/ig/gadgets/file/105066904960012479556/nccode.js'type='text/JavaScript'/>
2. Sign into Blogger then go to Edit HTML
3. Hit CTRL+F and search for: </body>
4. Paste the code directly above </body>
5. Save! Now, [im]http://yourphoto.com[/im] (replace yourphoto.com with direct link to image) should actually show up in a comment. Go ahead, try it out! But before that...
Go to Settings > Comments and scroll down to the Comment Form Message.
Write something like this:
Add images in your comment! Copy this code: [im]http://myimage.com[/im] and replace "http://myphoto.com" with the direct link to your picture.
It doesn't have to be exactly like that, but make sure it clearly states "[im]http://myimage.com[/im]" (You get the idea)
Until next time,
