In the top right corner of every topic, next to the 'Post Reply' button, you should now see a link that says 'Image Archive'. In threads where images are linked from another site, such as imageshack or photobucket, this link will lead to a directory of images which were saved by the automatic image archiving script. This script ran from April 2015 until November 2015 when the site was upgraded and it become possible to upload images directly to NerfHaven. Unfortunately, any embedded image that has been broken since before April 2015 or was posted after November 2015 will not appear in that list.
Due to a change in Imageshack's policy, pretty much all images linked from there will now be broken. I am working on a solution that will seek out these image links in old posts and replace them, but it may be some time before I get around to completing it. In the meantime, just click the "Image Archive" link and open the images manually. Thanks for your patience.
