There isn't a built-in button within report studio for this. You will need to insert a button in an html item, if your consumers are running IE you can use

 document.execCommand('SaveAs','true','http://chartsfilename.jpg')

as the javascript for it to run. You will also need a way to dynamically derive the chart's url. I would imagine you'll need some javascript for this, without having an environment to test on currently I would point you to http://www.ironsidegroup.com/2011/09/27/ibm-cognos-and-javascript-%E2%80%93-part-ii/
