How can I access and manipulate local file system resources from a browser

Question

I need technology for:

a) From the browser, web page, select the user's file system (with its authorization)
b) Let the user select a folder and search for images
c) The folder can contain huge jpg images (up to 20 MB)
d) show a modified version , a very tiny version, based images inside the browser
e) play with thumbnails (reorder, rename, associate some parameters), interact with web pages
f) let the user choose which image will be uploaded g) when complete, upload the whole huge original file size

I can not use an external client.
No problem for plugins.

Is there any technology that can do this?

I decided to try to implement all the “local code” in Java (selecting a folder and image, creating thumbnails) and transfer the sketch to the server. Using the Ajax application, transfer the thumbnail to the web page where the applet is located and allow the user to interact with the thumbnail. At the end, try recalling the applet for downloading source files.

Are there technological alternatives to this approach in your view?

Answer 1

Since you are already using Java technology, if you want the end user to have Java, I would go with a signed Java applet . You can use Java Advanced Imaging (JAI) for image processing.
