3 URLs of images used on social networks are passed in absolute URL.
Note that I did not pass all the images in absolute URLs, but, it could be consistent to do so, but, if the images work, maybe a relative call is more efficient?
Remove the version of PrivateBin, at the end of each image. This apparently prevents the opengraph from working, and, so I deleted on all of the images, to remain consistent at this level. This will make fewer requests, and, anyway, the images are not intended to change with each version.
