I was in a similar situation with email. In 2005 or so I was migrating to new computer when I found a directory of photos I forgot to back up. Rather than burn them to DVD or upload them to my domain, I decided to just email them to myself. I sent a handful of images, then replied to that same email with the next 10, and so on, until the five dozen or so images were uploaded in a single email thread.
When I went to open the email on my new machine, the loading indicator just spun and spun until finally my browser crashed. When viewing an email conversation, Gmail will display previews of all the emails in the chain, including their attachments, which was causing my browser to crash. Next I tried connecting my Google account to Apple Mail, but Gmail's SMTP server would time out before the attachments were able to download.
After a while I forgot about the photos all together, until I randomly stumbled across them while searching my Gmail account for some other files I had sent myself around that time. At this point it was 2014 or so, and my browser was very easily able to open the messages so I could download the photos, which of course at that point I had zero interest in.
