alternates to system() and exec() in order to use ImageMagik?

[news]

My Web host apepars to not allow exec() and system(), as a line in my
script:

system("convert -scale 100x100 $uploadfile $toimage");

gives the error:

"Warning: system() has been disabled for security reasons"

Is there some other way to use ImageMagik (or is it GhostScript?)'s
"convert" command in PHP that may be safer and generally allowed by Web
hosts?

Thanks for any suggestions.

If system() and exec() are disabled, presumably proc_open() is too, so you're
out of luck. There's an ImageMagick PHP extension in PECL, you could ask your
host if they'd install that (but they probably won't!).

(GhostScript is a Postscript processor - ImageMagick is the image processor)

Should also mention that you may be able to use the GD functions, since
they're bundled with PHP - http://uk2.php.net/image

They're slower and not as good for photographic images as ImageMagick, but if
you haven't got an alternative...

Wow! Thanks; I had no idea PHP had such built-in image manipulation
processes.
Thanks!
