To enable this product in a buildout-based installation:
Edit your buildout.cfg and add
collective.uploadto the list of eggs to install:
[buildout] ... eggs = collective.upload
After updating the configuration you need to run ''bin/buildout'', which will take care of updating your system.
Go to the 'Site Setup' page in a Plone site and click on the 'Add-ons' link.
Check the box next to
collective.upload and click the 'Activate' button.
You may have to empty your browser cache and save your resource registries in order to see the effects of the product installation.

We want to implement these features at some point in the future:
- Refactoring of widget's UI
- Resumable uploads: Aborted uploads can be resumed with browsers supporting the Blob API
- Chunked uploads: Large files can be uploaded in smaller chunks with browsers supporting the Blob API
- Enable/disable automatic uploads
- Server side image resizing
- Server side file type constraint
- Asynchronous Module Definition (AMD) support
- Widget for "allowed extensions" option
- The main file; here you will find 2 important things: plugin initialization and inheritance of basic UI code with custom templates (e.g. every new file dropped in the file upload widget is going to generate a new row, here is the code for that).
- Converts canvas elements into Blob objects, is a polyfill for the standard HTML canvas.toBlob method.
- Load Image is a function to load images provided as File or Blob objects or via URL.
- The most basic version of the File Upload plugin, with no UI.
- Extends the basic fileupload widget with image processing functionality.
- Extends the FP version, adds complete user interface interaction.
- Used for cross-site iframe transport uploads a way of degradation for the XHR upload.
- jQuery XDomainRequest Transport plugin; enables cross-domain AJAX requests (GET and POST only) (not really used, its just there if you need to implement that kind of functionality).
- jQuery UI widget factory; very lightweight, flexible base for building complex, statefull plugins with a consistent API. It is designed for general consumption by developers who want to create object-oriented components without reinventing common infrastructure.
- It enables pixel level access to images from different origins. It works by sending a JSONP request with the URL of the image to the server. The server then converts the image into base64 encoded data URL and sends the image back as a JSON object. (what this script does, can be done with CORS)
- Check if constraints are in place before adding the menu item.
