PSB file can't save for web, directley..
It's another tip
Ctrl+A, Ctrl+Shift+C, Ctrl+N, Ctrl+P and Ctrl+Alt+S
Select All, Copy Merged, New Document, Paste, Save for Web
An image size step to reduce the number of pixels may also be required after the paste, before the save for web step!
All of this can be automated into an action.
Usually when a file is limited to tiff or psd or psb, that means it has layers, and can't be saved directly as a jpg or png for the web
Make a copy of the master, merge or flatten to a single layer. You will keep the master for future revisions.
Mode/bit depth can be another problem. The file should be typically RGB color mode/8 bpc for the web and not 16 or 32 bpc.
The only catch is this problem was posted in 2012, and not likely we will see feedback.
