which PS do you have?

If you have PS 6 or 7...look for this tool call "Measuring Tool"..it should be with the Eye Dropper tool.

Select the straightest edge you can find on your image...and use the measuring tool to drop for one point to another...

After that...go to "Image"->Rotate Canvas -> Arbitary...

if done correctly...you'll find that it already has a small angle which when you click OK...it will be straighten...but you'll have to do alil cropping to adjust...

try out different straight edges to find the one that's best suitable..

thanks for the tip.
actually i think thats more suitable for straightening crooked scans rite. my prob is actually more of a case where the image looks like it's bloated. i tried to use the distort-> pinch plugin but the results weren't very gd.
