I have 15 GB free on Google Drive and something similar on Microsoft OneDrive. Sharing files is as easy as dragging the file to a folder on my PC and right clicking to get a link that I can paste into email, IM, etc.
We launched a service recently (fast.io) that lets you publish that content from your OneDrive or Google Drive right to a CDN too. No storage limits, and 100GB a month of traffic. We aren't specific to image hosting, but if you want to host a meme on a CDN, it's similarly super easy.
How is IMGZ better?
