During a file upload I am trying to:
1) Create a thumbnail.
2) Resize the image.
Number 1 is not working
Number 2 is working, but only if number 1 is not used.
This is whats phpinfo says:
imagick module version 3.0.1
imagick classes Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator
ImageMagick version ImageMagick 6.4.8 2009-12-02 Q16 OpenMP http://www.imagemagick.org
ImageMagick copyright Copyright (C) 1999-2009 ImageMagick Studio LLC
ImageMagick release date 2009-12-02
NB: I can not use exec, because of security demands.
I have tried for ages to get it working, but no succes.
Upon succes I happily will remove my install of TimThumb, which doesn't fullfill my requirements.
So please, I do need help.
I apologize for posting the code, please remove it if need be.
Kindest regards
Sara
