The best place to save an image win forms app

Question

Hi, I am building an app that will/does save an image via a picturebox, i will be using a remote database. before i have done this by using (blob) direct to the database but is this bad practise as it seems to be a large file in the database and as it grows will query lookups start to get slow?

I know web designers usually save the image in a seperate folder then only save the url in the database, can something such as this be done in a windows form app.?

So for instance, on the save command from the button save, then ftp the image to a web path/folder then generate a url to pull it in at a later date on it's query to be viewed in the picture box?

Thanks
