It was Indian independence day and all of my classmates (including me) decided to change our orkut profile pictures to the indian tricolor (flag). But some were reluctant since they just liked their profile pictures and had no copy of it with them so that they could reinstate it once the independence day is over. They tried to save the pictures from their profile pages so that they could reuse them. But as a measure to avoid abuse, orkut makes it difficult to copy someones profile picture (including your own)…..
And there the problem lies, some websites donot allow us to copy or download any images from them. They employ genius programmers and spend money to implement complex scripts that make copying of their images difficult. But for every problem that seems to be complex, there is a solution that is too simple to accept… this applies here too.
All you need is a firefox browser. Open the web page in which your image of interest resides in firefox.
Now right click anywhere on the page and select ‘View Page Info’. 
Or you can view page information by clicking on the favicon of the web page and clicking ‘More Information’.
Or you can simply select ‘Page Info’ from the tools tab. Now the Page Info window will show up. On it select the tab ‘Media’. There you will see a list of all images present in that web page.Clicking on any item in the list will show a preview of the image right in the window. Near to the display area, there is a button ‘Save As’ and save the image in your computer. That’s all.
Please let me know if you know any other trick.
