Been trying to download / save a graphic to use on a mockup and each time I try to find the graphic after thinking it was downloaded… it is nowhere to be found 
hmmmm, strange…I’ve been making cover photos and downloading product images all morning with no problem.
@igiftcenter it could be your network connection. I had the same problem - I was on my mobile hotspot. Changed over to my router and I could download
It wasn’t a Zazzle tech issue as you already knew. I have a 4 terabyte backup drive I use to store my graphics and backups on a second 2 terabyte drive. Turns out I had to remove and reinsert my 4 gig drive and all the download issues went bye bye.
Thank you for your replies
My apologies for the wrong explanation: as it turns out I was downloading my graphic to my default 4 terabyte drive but photoshop was looking for the file on my other 2 terabyte drive… and of course it wasn’t downloaded to that drive
