Seriously. I couldn't post images because I didn't have ten "reputation" points. Come on. I posted a link and then people who are able to edit had to turn it into an inline picture. Just, why?
- To prevent spam (yes I stole that from Braiam).
- It will take you mere seconds to get 10 rep.
- As you stated: If you dump the link someone with more rep can edit it into an image for you.
Otherwise we all would be deleting porn and other malicious pictures.
Please take the tour and you will better understand how askubuntu (or stackexchange sites in general) works.
It is not a bad system!
