The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

PHP GD image upload failing

Asked by JackHodson in PHP for Windows, PHP Scripting Language, PHP Installation

Dear all,

I have a script written for me by a member here some while ago.
I am using it on a new website and when I try to upload a large photo it is failing and comes back blank - it does not say the upload failed, simply it comes back blank (the header and footer of the website comes back but anything within the PHP does not.

For small photos it works well and uploads it to the folder.

I have tried increasing the following using a .htaccess file:
memory_limit to 100MB
post_max_size to 100MB
upload_max_filesize to 100Mb

still it did not work. the defaults are now set again and they are:
memory_limit to 24MB
post_max_size to 8MB
upload_max_filesize to 10Mb.

The code is pasted below and the php settings are here:
http://arockes.org.uk/images/user_photo_uploads/php_info.php

The uploader web page is here: http://arockes.org.uk/photo_uploader.php

PHP is something that does not make a huge amount of sense to me so if you could shed any light on this I would really appreciate it.

Kind regards,
Jack
