Batch Download Pictures From Website

Hi everyone- absolute noob here. What I am trying to do is download this image (http://radar.weather.gov/Conus/Loop/NatLoop.gif) to my hard drive every 85 minutes. Is there any way to do that with this program?

Thanks in advance!

I attached a little tool, it can help you run a PicaLoader project every xx minutes.
1. Download and install the latest version of PicaLoader (1.6.6 build 8768 now). Download attached zip file, unzip PLSchedule.exe to PicaLoader's installation folder. (default is C:\program files\PicaLoader)
2. Run PicaLoader, create a new project, then create a new task, start URL http://radar.weather.gov/Conus/Loop/NatLoop.gif
3. Exit PicaLoader, run PLSchedule.exe from PicaLoader's installation folder, select the project you just created, set time interval, then click start button.
