Hi,
I am trying to get an image to be displayed in one of four random
sides: right-sideup, on its left side, on its right side, and upside-down.
The problem I have is that I can only take a random picture saved
rightside up. The images are dynamically created by users and saved to
the database I am pulling from. I need to get the image and flip it to a
random side and display it in a random order with other images (flipped on
a random side) on the site. I can't seem to find any scripts that flip
images on their sides or upside down or anything. I was wondering if you
knew of any.
Jacob

JavaScript itself does not provide any way to do this, and neither does
HTML. Images can only be displayed as they naturally are.
Canvas allows something like this, but this is only supported on Opera 9 and
Firefox 1.5 (Safari 1.3+ also supports it, but generally has problems with
everything). Internet Explorer's filters may also offer something but they
suck, and they are non-standard and incompatible.
In general, you would be better off using a server side script to generate
new images in their rotated position, and display them. There are unix
command line image processors for doing this. The GD library has direct
integration from PHP, assuming your host support them:
