I understand your problems here. When we had the Image Uploader on the site, it was easy for me to reduce the size of pictures to a more manageable and viewable size for everyone, obviously I can't do this now. I wish I could say more on this, but I've no news, and cannot say at present when or even if it will return. If it were to return then I would start reducing images to a more appropriate size again.
With regards to the problem of topics coming up unread when you next log on, it's down to the way that cookies are used by the forums software, causing random threads to appear as unread when you've already viewed them. There is a simple way of overcoming this however. After you've read all the new posts on the site, click on "My Home" at the top of the page, scroll down and click on "Mark all read", then click "Mark all posts as read" on the next page. This should stop the problem.
