Try www.textamerica.com
I've tried the others but this one it still way ahead of the competition.
To sign up it's free and you can create as many picture blogs as you like.
You can also sign up for a paid subscription which lets you customize your picture blog web page.
But why do that when you can still have it for free.
I love the fact that I can send a video file from my phone, camera or computer to textamerica and store it for free. I have yet to pay for service that other providers charge.
