problems with the image resizing feature

Hi, i'm having the exact same problem as one of your notice board users Olaf but the issue was never answered -

I am having some problems with the image resizing feature (foto_upload.php). Evevry time i upload a file it says that uploaded and processed. But i dont see the file(s) in my directory. Interesting thing is when i upload really small images like 150x100 it uploads. But as soon as i use bigger images nothing happens. I've increased the the 1Mb limit on the script upload file and the above issue seems to be resolved but i never get any errors!!!! - lke i thought too that with the foto script, that the images are resized for you aswell?


PLEASEEEEEEEEEEEEEEEE Can you please help me?

Hi - i've just noticed that when ($use_image_magick = true;) the script totally ignores the image size specs ( - i set the max width and height to be say 100*100 and upload an image say 500*600 and the script still uploads the image?? - i have noticed though that if i set var ($use_image_magick = false; ) from true to false, the resizing feature feature works? - can you tell me what exactly this variable is used for? - is it this program that is used to process the image? - and if its set to false, why does the iamge resize? aand what program resizes it?

If this variable is set to "true", the script is using imagemagick in place of GD to resize the thumbs (IM is much faster and more powerfull)
check http://www.imagemagick.org/script/convert.php

I also have problem with resize. I cant use image_magick on my host. So I put "false" in the use_image_magick.

And this works great until I use a bit larger files, not larger in bytes but larger in pixels (more than 2000px x 2000px). Because when I do that the file just uploads it doesnt resize it. And I dont get any error message, in fact I only get a blank screen.

It seams very strange since it works fine with smaller file, both the upload and the resizing.

And also I wonder whats the difference between this size-variables?

Code:

var $x_max_size = 300;
var $y_max_size = 200;
var $x_max_thumb_size = 110;
var $y_max_thumb_size = 88;

and this

Code:

$foto_upload->x_max_size = 300;
$foto_upload->y_max_size = 200;
$foto_upload->x_max_thumb_size = 120;
$foto_upload->y_max_thumb_size = 150;

you need with GD about 100MB of memory to resize a ~2MB foto, Cool?

Thank you for quick answer.

The strange thing is that it doesn´t seem to depend on the file size but in the amount of pixels.

I´ve tried with large files (2mb) with few pixels and it works. And I´ve tried with small files (500 kb) with many pixels (2000px x 2000px) and then it won´t work.

Anyway, I´m new in PHP (only asp before this) so I don´t now what your talking about when you say GD. Sorry :s
