So when I go on a thread, some of the pictures are just a picture of paper, and when I try to open it in a link, it just sends me to the dropbox "we could not find this" page. can anyone help?

It would help if you told us which thread, and which posts, for an example.

Because this is a very old forum, it is likely that older pictures simply do not exist anymore, due to image hosting sites closing up and people just deleting old images from their hosting accounts.

Are there any particular images you're looking for? If so, I or other users may be able to help if you link to the posts. It depends on what they are.
