[Phpwm] displaying images on screen

[Alex Mace]

I think in that situation you'll need to save it out to a file and  
write an <img /> tag into the html to access it - I don't think there  
is a way to output the picture as binary in the middle of some html.  
If you don't want to save it out, just set the "src" attrobute of the  
img to something like

rotateimage.php?filename=YOURFILENAME

and perform the rotation in that script.
