Adobe Photoshop and vertical parallax

I seem to remember that Photoshop could be used to bring the lateral sides of photographs to the vertical - a sort of stretch process to bring inward leaning walls for example at either side of a photo back to vertical, but can't find it in the Adobe help files.
Anyone remember how to do it, please?

A similar feature in Corel Photopaint...

A rectangular mask to cover the whole picture.
Do whatever you have to do to show "sizing handles"
Using the selection tool click on the image which for me will then toggle through sizing to 2-way pointers in the corners.

These can be dragged (one at a time) to the new shape.

Finish with a rectangular mask and crop to the mask to restore the rectangle

If you have CS2, it's 'lens correction' in the 'filter' menu.

Even Photopaint doesn't work quite the way I described!
If you are even a tad interested I can describe better how I just did it!

In Photoshop, make sure that you're not in a locked layer (like Background) or this function won't be enabled.

Click Edit>Transform>

I didn't finish my post! Here goes again:-

Click Edit>Transform>Perspective. You can now drag the handles at the corners of the image to adjust the parallax.

IMO you are better making the adjustment on just the background layer i.e. no other layers open. Just go to "Select" "Select All" now go to Edit>>Transform, my prefered method is then to use Skew, as you can then adjust the sides independantly. However if both of the vertical sides are equal then Perspective is probably the easier way
