Image setting and uploading

[Sharon]

Hello,

At the image setting, I set the following :

The maximum kbytes the uploaded can be. - 80000
The Max Image Width for uploaded image - 10000
The Max Image Height for uploaded image - 10000


However when I tried to upload a 7mb photo, it tries to upload. After waiting for a while, a blank page appears. It doesn't proceed to the next step.

What has gone wrong?

Thank you.

Hi Sharon

Sometimes your server can limit the maximum upload size, irrespective of the options set in administration. You can verify the maximum size by calling the phpinfo function from a php page hosted on your server, here is the syntax:

<?php
	phpinfo();
?>

Don't have this up too long as this contains some sensitive information, perhaps call it from a ghost page (a page not tied to your navigation, for example).

Hope this helps

Update - if it is set below the 7MB you need, then you'll have to ask your hosting provider to increase the cap for you (assuming you don't have full control). BTW 7MB is quite some size!

If you are getting a blank page then your script has used up all the memory that php.ini is set to allow your script to use.

The thing to consider with jpg image files is that they are compressed and during the image upload process images a thumbnail is made from the image and the image size is checked and resized if needed. To do this the image file needs to be uncompressed. A typical 7mg jpg images saved at %90 quality will be about 25mg when uncompressed. So, while a 7mg file passes PHP's setting of file size upload it will often exceed the php.ini setting of "memory_limit" for the script.

80,000 kbytes is about 78MB.
10,000 X 10,000 pixels is almost ten times the size that a typical 17" monitor could show. Why would you want to allow such huge picture parameters?
