There is an blue edit button that shows up near your post. The rub is that you can only edit your post for about an hour after it is originally posted. After that the edit button disappears and the post is out of your control. If it is critical to edit it you can appeal to the moderator of the section in which you posted to help deleting/editing it.
I have a similar question, what do i do when my upload limit is reached? I tried to delete old attachements but don't find a way to do it?
You may find if click once on the "User Controls" on the highlight bar and then when it drops down the options, scroll down and click on the "Settings" word, then scroll down to the left hand bottom side of the page and find "Miscellaneous" just below that you will then find "Attachments" click on it once and it should open up showing your attachments you Posted. Failing that Samy it might be time to Subscribe if you can't delete your old attachments I just checked mine and it's saying "You are currently using 146.91 MB to store 1,893 uploaded attachments"
You have to subscribe to upload more pics after the free limit is reached. Silver subscribed for either $15 for 1 year or $50 for 5 years. Unless you plan on losing interest in Ferraris this is the way to go. BT
