Requirements

Mandatory requirements

• jQuery v. 1.6+
• jQuery UI widget factory v. 1.9+ (included): Required for the basic File Upload plugin, but very lightweight without any other dependencies from the jQuery UI suite.
• jQuery Iframe Transport plugin (included): Required for browsers without XHR file upload support.

Optional requirements

• JavaScript Templates engine v. 2.5.4+: Used to render the selected and uploaded files for the Basic Plus UI and jQuery UI versions.
• JavaScript Load Image library v. 1.13.0+: Required for the image previews and resizing functionality.
• JavaScript Canvas to Blob polyfill v. 2.1.1+:Required for the image previews and resizing functionality.
• blueimp Gallery v. 2.15.1+: Used to display the uploaded images in a lightbox.
• Bootstrap v. 3.2.0+
• Glyphicons

The user interface of all versions, except the jQuery UI version, is built with Bootstrap and icons from Glyphicons.

Cross-domain requirements

Cross-domain File Uploads using the Iframe Transport plugin require a redirect back to the origin server to retrieve the upload results. The example implementation makes use of result.html as a static redirect page for the origin server.

The repository also includes the jQuery XDomainRequest Transport plugin, which enables limited cross-domain AJAX requests in Microsoft Internet Explorer 8 and 9 (IE 10 supports cross-domain XHR requests).
The XDomainRequest object allows GET and POST requests only and doesn't support file uploads. It is used on the Demo to delete uploaded files from the cross-domain demo file upload service.

Custom Backends

You can add support for various backends by adhering to the specification outlined here.

Browsers

Desktop browsers

The File Upload plugin is regularly tested with the latest browser versions and supports the following minimal versions:

• Google Chrome
• Apple Safari 4.0+
• Mozilla Firefox 3.0+
• Opera 11.0+
• Microsoft Internet Explorer 6.0+

Mobile browsers

The File Upload plugin has been tested with and supports the following mobile browsers:

• Apple Safari on iOS 6.0+ (see Caveats below)
• Google Chrome on iOS 6.0+ (see Caveats below)
• Google Chrome on Android 4.0+
• Default Browser on Android 2.3+
• Opera Mobile 12.0+

Caveats

• iOS 9 has a known bug where photos chosen from the Photo Library are all given the name image.jpeg, which is problematic when uploading multiple files at a time. Ideally your server should be responsible for deduplicating file uploads (example). If you don't have control, as in the case of direct uploads to S3, you can pass an option uniqueFilenames: {} as part of the options object, which tells the uploader to deduplicate filenames.
