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 PHP Image Library +===================== +Elgg requires GD for image resizing of profile avatars. 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 anyway. GD is a memory hog and will cause problems with large images. + +imagick PHP Image Library +============================= +A significantly better image library than GD. Not as common as GD. You may need +to ask your system administrator to install this. The server info tab in Tidypics +settings will tell you whether it is installed. + +ImageMagick command line tools +=============================== +This requires that the PHP function exec() is available which is often disbaled +for security reasons. You can find ImageMagick on your server by running "which convert". + +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. Subtract this number from the total amount of memory available +for image processing. Remember that GD requires a lot of memory - more than just the +size of the image. + +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 with the basic uploader. +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 +=============== +This tells you whether you can resize JPEG images with GD + +GD imagegif +=============== +This tells you whether you can resize GIF images with GD + +GD imagepng +=============== +This tells you whether you can resize PNG images with GD |
