The simplest way to download an individual file that was previously uploaded is usually to view the file in your browser and save it.

There are several ways to download an image at a different resolution than the resolution of the uploaded file. If the image is being displayed at the resolution you want, then use your browser's method for saving the image; otherwise, you can generate the image on a page of your choice (e.g. Sandbox) and then download it. E.g. include a line such as the following:

  [[Image:SomeImage.jpg|120px]]

See Help:Images for further details.

A PHP script illustrating how to download an entire MySQL table is here. There are two ways in which such scripts can be made available through QED:

1. The script can be included as a PHP file.
2. Logged-in users can embed the PHP code within <php>...</php> tags and request that the page be protected.
