Server Configuration ----------------------------------- Run your server analysis located in the Tidypics Administration section and then read through this document. If you are experiencing errors, please check your server error log. Tidypics writes warnings for most upload related problems. You will see something along these lines: "Tidypics warning: user exceeded post limit on image upload" GD: Elgg requires GD for image resizing. Tidypics uses GD by default for resizing. There are two versions GD and GD2. It generally does not matter which one you are using and it isn't always apparent which one you are running anyways. ImageMagick: A significantly better image library than GD. It uses less memory during resizing. Use this if it is available. Memory Available to PHP: The amount of RAM available to a single PHP process. This can have an effect on how large an image you can resize (especially if you are running Tidypics with GD). The best place to change it is .htaccess. Memory Used to Load This Page: This gives you a baseline of how much memory is being used to load the Elgg framework and plugins. Max File Upload Size: The largest file that can be uploaded. You can adjust this in .htaccess. Max Post Size: The largest amount of data that can be submitted. For Tidypics, this affects how many large images can be uploaded in a single upload. If this is exceeded, nothing is uploaded and the user gets an error message. It can be adjusted in .htaccess. Max Input Time: This is the amount of time PHP will wait for an upload to finish. Your users may experience failures if they are uploading large images on a poor connection or if your server does not have a lot of bandwidth. Max Execution Time: The longest time a PHP script can run on your server. If a user uploads many large images, the resize code may take a long time to complete and will be stopped by PHP. If you are seeing problems with this, you probably have a slow server. GD imagejpeg: jpeg resizing with GD GD imagegif: gif resizing with GD GD imagepng: png resizing with GD
