When you upload the picture, do you do any processing on the picture? Or do you upload it just as any file?

If you do some image processing, such as resizing, a 1MB image will require quite a bit of memory for PHP.

I would say that you run out of memory. Try increase it in your php.ini: memory_limit = 64MReply

Hi Colin, thanks for your reply, appreciated.

Unfortunately i can't change the memory, i use a shared webspace.

After trying for hours, I am not sure it is a file size problem. I reduced one image to 600Kb but left the dimensions to 2272px wide......it gave same problem.

I am trying to upload images and yes using your script to first resize width to:

$handle->image_x         = 1000;

and then creating thumb:

$handle->image_x         = 200;

I echoed a statemement that proved it uploaded to the tmp folder but wouldn't echo this:

if ($handle->processed) {
            echo" everything was fine !";

Is there anything you can think of? or a way around it? Would be very grateful.

Kind regards

It is actually a file size issue. It is also a file dimension issue.

The dimensions that you want (2272px wide) are too big for the memory you have available. What happens is that the class (GD actually) converts the image into a bitmap before resizing it, or compressing it. A bitmap will require a lot more room than the JPEG version of the same image.

So if you have a file with a great dimensions (a lot of pixels), and even though the file size is small (in KB), the class will require a lot of memory to process your image.

There is no way around but reduce the dimensions of your picture, or increase the memory limit on your host.Reply

Colin, I'm with that problem, apparentenly, how do I solve (I'm using Apache)?Reply

See the first item on the FAQReply

Forgot to add......

Script works fine with images of around 1200px wide and less than 1 meg.Reply

These 1200px probably represent the maximum dimension of your picture if you want to resize it with the amount of memory that you have available.Reply

Sorry also forgot to mention.................
Don't know if relevent, but even when it all works fine, I get no info. Below is from an image i just uploaded successfully. It is typical

source is an uploaded file
- source variables  
  file_src_name         :
  file_src_name_body    :
  file_src_name_ext     :     
  file_src_pathname     :     
  file_src_mime         :     
  file_src_size         :  (max= 75497472)    
  file_src_error        : 4

If the upload works fine, these variables can't be empty. Make sure you are printing out the right logs, for the right call to process()Reply

Thank you Colin. I will see if my web host will increase the memory to 64.

In the meantime I will reduce the file size to less than 1000px.

Very much appreciate your help and quick replies. I also want to say thanks for your script, it's fantastic and the thumbnail creation with dropshadow is great!

Kind regards

Drop shadows? You mean reflections, right? ;)

I plan to implement drop shadows at some point.

If you like the script, you can contribute by rating the class on the sites such as PHP Classes or HotScripts, writing a review on a blog or even donating my a little bit!Reply

sweet. that solved my problem, too.Reply

Cool!

And thank you for your donation.Reply
