At the very top of TRT in the header image on the right. "Photos". Then I would goto 'upload photos' and then possibly have to login again ( This raised suspicion of another server to me ).
Then, in "upload photos", there's a green/red bar and directly underneath that is that info...here is what it says today:
Disk space allowed on your account: 102,400kb (104,857,600 bytes)
Disk space used on your account: 2,137,541kb (2137541 bytes)
Disk space remaining for your account: 100,313kb (102720059 bytes)
I'm pretty sure I haven't used 2.1 GIG's

Especially with I'm only allowed 104 MEG's

The function that calculates that is simply not moving the decimal accordingly apparantly. I'm a programmer and I've made that mistake millions of times...actually this morning ( just kidding )
