Image server for Wordpress

I have a new screen shot of my desktop from my PC daily. Now I would like to share this image at my Wordpress homepage. I was thinking some software solution at my Raspberry could host the image and create a http-Adress for Wordpress to show the picture at my homepage. But the image server at my raspberry has to do an autosync with my PC.
Is there a tiny solution a image hoster?

Daily image of my desktop ---->autosync or copy-----> Image server at my raspberry -----> daily new picture is shown at my Homepage

You could install SAMBA and a WebServer on your RPi. Using SAMBA, you could mount a share on your Windows PC and store the picture directly on the RPi.
