Hello,
I am a new bee in developing large java projects so need your help in this regard. As a part of our project we need to upload a image to a site(say picasa) or any photo sharing site. I would like to know whether it is possible to retrieve that image for that particular site & can be used for further processing.If this is not possible please suggest some ways by which this can be implemented.

If you can get a clean URL for the image on the site, you may be able to read the image from the site the same as a browser would be able to read it. Some sites require you to spoof them into thinking you are a browser.

You may want to use Commons FileUploadlibrary. Linked site also includes some examples/tutorials
