I don’t see the download link in my collection
The .zip file is created once the collection is sent to the client. In draft mode the link is not visible.
I get an error 500 when sending a collection
If you have a huge collection, and/or the images are very big, you might run into memory issues on your web server.
You can increase the memory limit that WordPress can use by adding this code to your wp-config.php file:
You can check, how much memory you can theoretically be using by going to “picu > Settings > Debug Info” in your WordPress Admin and look at the “PHP memory limit”.
If it is already set to the maximum, another option might be to upload smaller images or split your images into multiple collections.
I get a “Not supported” warning and can’t select the “Atomatically create .zip file from collection” option
The PHP version on your server does not support the ZipArchive class, which picu uses to create the ZIP file from your images.
Check with your hosting provider on how to add support for that class for the PHP version you are using.
Still having issues?
