Your image has a rather odd resolution.

Image: img1.png
   Format: PNG (Portable Network Graphics)
   Class: DirectClass
   Geometry: 250x250+0+0
   Resolution: 0.39x0.39
   Print size: 641.026x641.026
   Units: PixelsPerInch

So your png is 250/0.39 = 641.026 in wide.

That is 46153 pt which is larger than \maxdimen. Change the resolution 
and your image works fine with \includegraphics.
