Do you take a lot of photos with your phone? It's a pretty handy thing to always have that camera with you. Not only is it easy to share vacations and outings, but more "serious" stuff as well: here's the apartment we're looking to rent; here's the cute new dog we're looking at adopting from the local animal shelter.
You can send those images to other folks through MMS, but if you're hitting more than one or two contacts, that can get expensive. It'd be handy if you could hit a bunch of folks all at once.
You've got an online account for sharing pictures, right? If it's with Photobucket, you can take advantage of their service that lets you upload pictures directly from your phone.
Log in to your account, click on the "albums & upload" button, grab the email address and send a message to it with your picture as an attachment. In a short time, your image will be included in your album. Now you can point people there to see your handiwork.
If you don't already have a Photobucket account, you can sign up for free.
