Batch resize & compression
Hope this is not wont offend by talking about 3rd party software!
Picture Resizer 3.0
I found this neat little utility the other day to batch compress and/or reduce file sized. It can run from the desktop and also from the contextual menu which is really handy. I'm sure some of you might find it useful. Haven't tried it with panos yet, but works well with stills.
