can't create simple image from php exec , can create with the same command as standalone

Question

I have this code running in CentOS 5.5 ,PHP 5.1.6 ,Apache/2.2.3 ,ImageMagick 6.2.8

$convert = "/usr/bin/convert";
$command = "$convert -size 100x100 xc:blue mytest.jpg";
$test_image = exec($command);
echo "<img src=\"mytest.jpg\">";

when i run the php tester i dont get the image created , only the echo string printed on page as html.
but when i run the same command as onliner the image does created just fine.

/usr/bin/convert -size 100x100 xc:blue mytest.jpg

what is wrong here i can't tell.

Your PHP assumes that the web server has permissions to execute programs and to write to the current directory. You should use popen() to send the image to stdout and either use the data: scheme to embed the image data into the HTML, or put the PHP script as the src for the img tag and output the appropriate header and then the image data.

Does PHP, the user, have permission to do that?
