I found this, which *should* make using Google slightly easier.
I've seen NOTHING that makes me think they're a good host, so i'm not making an account to test it out.
Everything i've seen makes google seem like a bad choice and it's run quite a few new people off message boards because it's too hard to actually make it work.

Upload to Google Drive
Right-click the file(s),
select 'Get Shareable Link', which will be in the format like
https://drive.google.com/open?id=1uN...rjC2LrDfsrJpgv
Substitute
'https://drive.google.com/open?id='
with
'http://drive.google.com/uc?export=view&id='
Now you can use this URL to insert into the img tags.
Or just get arother image host that works better/easier, and does less data-mining on anything you ever let near them.
