upload via FTP only 1 ( one) still image at a time

Hello ,
I'm using a Hikvision ip camera

Model: DS-2CD2125FWD-IS
firmware: DS-2CD2125FWD-IS
Web version: V4.0.1 build 190506

Is there a way to upload via FTP only 1 ( one) still image at a time and overwrite it for example every 1 minute.?
I need this for uploading and updating a webcam image on my website.
Normally the camera sends each image with a different name in a daily folder on my server. What I really want is to have only one image each time and use it to show on my website.
