I recently swapped my hosting to squarespace. I've known about squarespace since 2010, and I've been looking for an excuse to switch. Squarespace 7 platform was that excuse, as well as the bill for former host. Unfortunately, this means that some of my clients' work and personal work isn't available for hotlinking like it was before. I'm able to do a tiny bit of url mapping, but I'm not quite sure how powerful it is.
So, if I've done some work for you in the past, go ahead and email me. I'll send your files right over. If you want to hot-link your images like before, we can work something out.
