bad dc inside link
A post whose source is a direct link to a DC Inside image, rather than to the DC Inside post containing the image. These are considered bad links because there's no way to find the original DC Inside post from the image link.
If you see this warning while uploading, it means you should paste the link to the DC Inside post on the upload page, not the image itself.
