Galleries features

Use database to store images

Use directory to store images

Choose Storage Location: You can decide for images to be stored either in the database, or in a folder on your webserver. Storing images in your database is OK for small images, but a folder is recommended for a high volume site or when your images are relatively large. Note the trailing forward slash in the path entered in the above graphic, but also here in red. Be warned, if you want to restrict access to the images, you have to choose a folder that is not browsable (not inside the document root of your webserver).



Path characteristic checklist:

• Has a trailing slash.
• Is specified from the root.
• Is in a separate folder from Tiki, for better security.
• Has its permissions set (e.g. via the chmod command) to allow uploads by the webserver user.
• Has enough space to allow storage of your expected image volume.

If you take a look at your folder after uploading some images, you can see that Tiki randomizes the filenames, as shown in this graphic:



Troubleshooting Tip: If you are having trouble with image uploads, you can edit settings in your php.ini, or, place an .htaccess file in the root of your tiki installation.



Troubleshooting Tip: If you encounter random errors and webserver crashes, you may have updated your apache, but forgot to update/recompile your graphics library. The apache error log will give you some hints..

• GD
