Keep in mind free hosting services use hugely shared cheap servers so it wouldnt be unheard of to have sometimes slow or loss of access. If its more than just one day then you might try to figure out what else is going on.
Can you post a link to one of your photos here?
No, its quite strange. I can log in and some of the tabs work and others dont. I can click on library and it will take me there, but it's like the page doesn't completely load and no photos show up. I"ll see if it's still doing that tomorrow. I sent them an email about it, they dont have a contact phone numer. It seems their support is about as much as a broken jock strap.
