- Troubleshooting
- =================
- 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 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 disabled
- 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
