Hey Midnight with your quality pics I thought this would help out.
This way it posts them nice and big looks great.
Go to your profile and on the left underneath your friends list is a place to add albums...
Create a new album and upload all the photos you wish to use.....
You will need two tabs open to make it quicker... One tab should have the thread you are posting to and the other one should be your photo album.
Once all the photos are uploaded click on a photo you wish to post.... Down the bottom of the photo are two codes are url code and a bb code... Copy the bb code only and paste it in the required thread.... Do it for each individual photo
