Can anyone tell me which is the easiest site on which to publish

If you already have a google account (e.g. for gmail, or an android
phone) you can use Picasa Web Albums

Or Flickr?

Plenty of others, but the "low end" sites like imgur, tinypic and
photobucket are a painfully full of adverts, flash and even malware, so
best avoided.
