I appreciate that the limitation on new users posting images is there to prevent spamming by bots but I'd like to suggest adding a mechanism that allows moderators to manually enable image posting for users where it's clear from their first couple of posts that they're not a spambot.
There have been a couple of occasions recently where new MR2 owners have signed up and wanted to show us pictures of their car but been prevented from doing so.
They then have to start spamming the forum in order to build up enough posts to be allowed to bypass this anti-spam limitation which seems a little counter productive to me!
