I have a web page/script that displays image files residing on disk. I
do not know what size they are (in pixels), so I want to be able to
resize an image if it is bigger than the limit I allow (say, 900 pixels
wide).

I want to create the resized image in memory and serve it directly,
without saving the resized image to disk (they are only temporary, and
I'd rather not worry about cleanup). I know how to use some of the GD
library and I also know how to use ImageMagick. I would prefer to use
ImageMagick, as it has a good quality Unsharp mask (usually needed after
a resize/resample of an image), but I don't know if it is capable of
doing this (creating the image in memory so I can serve it directly
without saving it to disk first).

Using the GD library, I need only use a header to set the MIME type and
then imagejpeg to serve the resized image directly from memory.

Does anyone happen to know if I can I accomplish the same thing with
ImageMagick?

Also, ... does anyone know of any good tutorials or scripts for
on-the-fly image editing (ImageMagick or GD lib)? (This is a pretty
good one: <http://codewalkers.com/tutorials/42/1.html> Any others? Any
that use ImageMagick?)
