Reduce the weight of a high resolution image online

Question

I am in need of a high resolution images but that is not the problem.I have many high resolution images which are truly free online but their weight is a hinderance for use on the web.For instance,a good image with 1920px by 1080px is weighing in at 1.2mb yet i see images of similar dimensions i.e http://farm4.staticflickr.com/3241/3096487740_ebb4ea9819_o.jpg that weigh a lot less (175kb).

Is there a suitable and reliable web service that can help me reduce the weight of a big image like http://www.rgbstock.com/filedownload/krappweis/nX2zg5e.jpg

Thanks.
