Is it possible? or is a security lock from browsers? Both. It is possible, but only if your browser allows it. I am using $.post() It is likely that you won't be able to POST to a JPG file. You should use GET. For example, on my local web server i can POST to HTML files, but on my hosting provider i cannot - i have to use GET for HTML files. So I could send the path that user choice C:/Users/example.JPG to my php and return img width=50 height=50 src=file:///C:/Users/example.JPG/ Imagine what would happen if any JavaScript could read a local file and then POST it back to the web site. Scary stuff. But isnt working because browsers cant show this tag img width=50 height=50 src=file:///C:/Users/example.JPG/ As well it should not. See above. I can upload the file to webserver I know but will be more fast and I can save some bandwidth traffic if I could do this. And avoid malicious users consume my bandwidth traffic. But this feature is far more malicious than bandwidth theft. So Jquery can show Images from file:///C:? or something like this? This is not a question of jQ, but of JavaScript and the browser's security settings. i would NEVER enable my browser to allow reading of local files. i don't even think that Firefox lets you configure it to do that.
