Steve, just host them here on the board, then they will always be around. I cannot tell you how many cool threads I have read through over the years where people used Photobucket, AOL photo album or so other horrible hosting service and the thread was ruined because all of the pictures to which the text refers have gone missing.
Pirate and Mud both allow you to buy extra storage space if needed and I know you are a smart guy with computers and tech, so I am sure you will come up with a solution for this. The premium account may be worth doing to keep everything here. I am sure we could get a few people to chip in and cover it if needed.
Another option is to buy your own domain (do not use GoDaddy) and host the images there. You do not need to actually put up a website in order to host pics. Just dump them into a folder and use IMG tags to display them.
