I don't that is possible if they are posted within or through AA. If pics are removed then there will be threads with missing pics.
You could open an account with an image sharing site such as PhotoBucket or Imgur. When you post pics to those sites, the URL should be made available to you for sharing/posting (that's the high level description).
If you have a paid membership, then I believe you can post more images with AA. The annual fee pays for certain perks
