Does anyone know of a good free bulk upload tool for web apps?

I have a web application in which a user has to upload images to a gallery. At the moment they need to upload one image at a time so it's pretty tedious.

I'd like to implement a system where they could potentially drag and drop files into the browser开发者_运维技巧, or select a folder to upload.

Any ideas?

Thanks in advance!

(By the way; it's a .Net App if it makes a difference, but I was thinking most of the work would be happening client side so shouldn't matter)

SWFUpload is pretty nice. It can select multiple images in the select dialog. It relies on Flash.

There are a number of other Flash-based uploaders around (they all make use of Flash's upload capabilities, which in addition to bulk uploads include things like progress bars, client-side resizing (Flash 10+) and file type filters (.jpg,.gif)... SWFUpload is certainly one of the most complete solutions.

Is SWFUpload the kind of thing you're looking for?

From their site:

SWFUpload is a small JavaScript/Flash library to get the best of both worlds. It features the great upload capabilities of Flash and the accessibility and ease of HTML/CSS. See it in action.... Upload multiple files at once by ctrl/shift-selecting in dialog Javascript callbacks on all events Get file information before upload starts Style upload elements with XHTML and css Display information while files are uploading using HTML No page reloads necessary Works on all platforms/browsers that has Flash support. Degrades gracefully to normal HTML upload form if Flash or javascript is unavailable Control filesize before upload starts Only display chosen filetypes in dialog Queue uploads, remove/add files before starting upload

You can also try Plupload. It's open source and has modules withing with Flash, Silverlight, HTML5 and HTML5. Depending on module used, it supports file upload using drag & drop, upload queue, client-side image resize, etc.
