Visual Studio Publsih Error.

Question

 I often get this error whenever i try to publish changes to one of my website from visual studio using FTP and have to switch to fileZilla though i want to publish only changes and want VS to do it for me but i don't get any success.

 

Preparing to publish files...
Connecting to ftp://mysite.......
Unable to add folder 'Images' to the Web site. Cannot create folder "Images".

 

But there is already a folder named images in my server with more that 2000 images in it. I just wanted to upload more images and got this error.
