The biggest issue is it requires Java Runtime, and I've disabled Java in my browser to save Firefox the trouble of doing it every 5 minutes, so I can't act surprised if our users don't have it or want it. Also the Java detection isn't very good, Java detection is harder than it should be.

I'd like an uploader that; uploads regulars files, will scale images down client side (JPEG, GIF, PNG), can upload and resize a bunch of photos in one go with some sort of progress indicator. Free software (as in freedom) preferred. If it spots a mobile browser or phone and does something plausible that would be brilliant. Needs to work in current browsers (that includes IE8 still — no really some people still use it), but otherwise latest stable Chrome, and Firefox (We have no issue with telling people to upgrade their browser if a newer version would work better AND is available for their platform). Drag and drop highly desirable but if it opens the appropriate (native) multi file select dialog box then we can survive without drag and drop.

Best candidate so far is "plupload" — doesn't appear to have a switch for setting upload resizing client side — but that looks fixable as long as all the images in one upload are the same size, which is probably acceptable for our purposes. "plupload" can fall back to all sorts of exotic backends, but that is fine, as long as if I have a modern browser it "works" without them. Fall back to something for IE8/IE9/IE10(?) is almost mandatory. We already fall back to a simple HTML form when the users despair of Java or we don't detect Java.

I've looked at: Uploadify (no resize of images), SWF-Uploader (dying), GWT-Uploader (seems to be revamped SWF-Uploader), Silverlight File Uploader (obvious issue here), ThinFile Upload (Java and demo died), Agile-Uploader (seems to lack love), FineUploader (No image resize), and some other less notable uploaders.

Can /. reader tell me if I've missed one worth examining. Or should I look to browser plugs and mobile Apps."

  • Good luck finding a program that will reliably resize images client side and then upload.

    But while it is understandable that you want to keep the load on your server as light as possible, there is already good server-side code that does this quickly and reliably. In fact, if you have a Linux server, it probably already has ImageMagick installed.

    It is very easy to create a server-side app in Ruby, for example, that will take an upload, resize it to one or more custom, named sizes (including various thu
  • you just need a client side language with an implementation of php gd's "imagecopyresampled" function

    gd is open source, so it might be possible to implement it with a html5 canvas, but efficiency would take a hit

    start with https://bitbucket.org/pierrejoye/gd-libgd/src/ [bitbucket.org]

    i would argue that if you can't program a web client with a combination of html4.01/5, css2.1/3 and javascript, you're doing it wrong

      as far as reading the file, the html5 file api is supported by chrome, which will get you a notable and increasing chunk of web users

      ie and firefox will catch up soon
