The only problem with Smugmug is that you have to have a pro account and its a $150 bucks a year. If you are just a hobbiest and not trying to make money on your photos its hard to swallow that kind of money.
Not true, I just had a friend get an account and I told him to Google Promo Codes for discounts for Smugmug
He sent me an email back saying he found a discount code for $75 off the Pro Account price. For how simple it makes it, that's totally worth it for anyone who has large amounts of photos
Plus, and this is a huge plus, you upload your files to their site full res. so you basically have an offsite storage for your images also. This is really important for those of us who travel non-stop.
Not trying to sell anyone on Smugmug, but for everything they offer, they make digital storage easy for us Overlanders
