ok.
Dropbox is not a solution coz you are looking for cloud storage.
one thing i would suggest you based on personal experience. get over the idea of free online storage. services disappear just like that (link-removed).
lightbox i think has no limits. but they would eventually have to figure out a
business model. free does not really work out well for the service provider which means that the end user ends up suffering.
stop being a bit lazy. get a storage account on
google plus. sync everything in the cloud. put a weekly/monthly alert on your phone to download everything on the PC and upload it to the cloud using picasa.

flickr has unlimited online storage for 25 dollars per year. i have used it for years. it is great for photos. not for videos though as they only offer 90 second clips. nothing larger...
you can perhaps think of using skydrive (25GB free)... but my personal experience is going to suggest google storage. videos up to 15 minutes are free (whatever quality) though they do not make them available for download.
photos up to 2048px are free. 80GB for 20 dollars per year is a pretty solid deal.

Metago | ASTRO File Manager Overview
Astro is another option you might want to check out. They have a free account. I am not sure about the details. But the point remains, no business is going to offer a free cloud storage that can be trusted for a long time to come.
I switched from Flickr to Picasa just because I am sick of how Yahoo has ruined Flickr. And Picasa has better support on the
Android platform.
