Hi - I'm new here, having looked around at various picture threads I only see pictures and no links to zip or rar files for quick download. Is this not permitted?

Before I start posting I just want to be sure whether I can post links - rapidgator, fboom, zippyshare etc or whether I should only post thumbnails of the actual images?

If a set has say 100 images and I can post a link - do I still need to post all 100 thumbs or a selection is ok?

I had a look around the posting guidelines but couldn't find anything that answered this.

Thanks
