saving rotated pictures in gallery

[youngmoney]

I have Saved MMS. One problem I'm having is that the pictures I save in SavedMMS don't always go to the gallery so I use ASTRO to find the pictures. Once I find the picture, I would love to rotate it into portrait mode and SAVE the rotated state. I want to set the pic as my wallpaper but it's sideways each time I do so. How can I make the pic portrait mode and save it as such? Thanks!
