The more information you give, the easier it makes it to try to identify the image type. What is used to capture the image (what software/hardware?). Is the image supposed to be able to be read by something else? etc.
Just from your size statement, we can infer something:
A 1600 x 1200 x 3 bytes (24-bit) is 5 MB of data. As your file is only 150 kB, it is heavily compressed. Possibly something like jpg. Problem is it's not a standard jpg file.
Your file appears to have some sort of header, but I would expect the size of the image to appear early in that header but it's not there. What it starts with, though, is possibly a date: 5/10/2015 ? and maybe a time 17:02:24.
No idea what the rest is. In any case, your file is not a standard image format so without more information, it's going to be very difficult to decode.
