Using pixels to set the width, due to the image's high ppp --as Muccigrosso 
discovered--, should produce an image of 0.22 in (600/2785). 
With LaTeX you can specify the tall AND the width, and if you want to 
preserve the image proportion its preferable to set one dimension 
(horizontal or vertical) and 'keepaspectratio' in \includegraphics[ ... ] 
instruction. The easy thing is to use 0.9\linewidth as the image width. 
This way, your image **almost allways fit** in your document (except for 
very tall images).
