Hi there.
i want to setup an ftp in that i want to install a software with which i can view the images with out the need of downloading it. so can any one tell me is this possible or not.
Thanks

Well you could describe the thing a little better; integrate software to where? ftp server? client? In any case, it's physically rather difficult to see an image from a remote server without downloading it - even if you wanted to see a thumbnail, you would first have to fetch (download) it, before being able to see it. You could make it so that the image (or thumbnail) is downloaded to a temporary directory for viewing, and deleted from there after the connection is cut off, for example.

Just as when you view an image in a web page, that image is downloaded before it's displayed. You just don't "see" that happen, because it's downloaded to a temporary/cache directory.

This isn't really something that you can do with FTP protocol. It is best suited for HTTP.

As the others have said - it's impossible regardless of what protocall you use (be it FTP, HTTP, SMB, etc)
The data would have to be downloaded in one form or another - otherwise you'd be expecting the computer to psychically predict what the image should look like.
