I think your picture will always be square; all you can do is overlay a mask or something to make it seem round.


<?php
// Create the mask - in this case a circle but could be any shape, make sure the mask is large enough to cover the whole image
exec("/usr/local/bin/convert -size 200x200 xc:none -fill blue -draw 'circle 100,100 100,13' circle.png");
// Use the mask to remove everything apart from the circle move the mask where you want with -geometry +0+0
exec("/usr/local/bin/composite -compose Dst_Out circle.png -geometry +0+0 image.jpg -matte new_image.png");
unlink("circle.png");
?>

Imagemagick method, from memory the background should be transparent; may need to make it a gif instead of png but you will get a colour if you save as jpg. I would guess if you want to save as a jpg you would need to change xc:none to your page background colour.

God knows what I have done but the PC has gone mad doing things I do not want it to do !

I hit the Ctrl key and another one and now can get out of whatever is happening.

Imagemagick is free but depends if your host has it installed; it can deal with most image formats without setting different codes for different types. The other major image manipulating software is GD library; which I do not know so much about.

Put this code onto a page and run on your server to see if you have ImageMagick installed:

<?php
  header("Content-Type: text/plain");
  system("exec 2>&1; type convert");
// Output: convert is /usr/local/bin/convert
  system("exec 2>&1; convert -version");
// Output: Version: ImageMagick 6.2.8 06/10/06 Q16 http://www.imagemagick.org
// Copyright: Copyright (C) 1999-2006 ImageMagick Studio LLC
?>

It should display the info but may ask you to download a file which will contain the info.
