You can try this site if it's a jpg file: http://www.jpegmini.com

Alternatively open the image in an image editor such as photoshop and resize/scale/stretch. Play around with it and see if you can get a smaller pic while keeping the best quality you can.

It shouldn't be too bad if scaled down (scaling up is painful). Just remember to keep the dimensions the same.
