It tells me that the actual digital data output needs to be checked byte by byte. Checking the image to see if it seems wrong (not so much right) is a useful tool, but close isn't good enough. That's why it's ...

{
fread(&buffer[i], 1, 1, raw);
}
Here's what's happening. The fread() call reads exactly one byte and stores it in one element of the buffer[] array. But, each element in the array is 4 bytes long! The remaining bytes are ...

My browser didn't crash (Firefox), it gave me a popup error message after it timed out. Yours may have actually crashed, I can't explain that.
However, if you right click on the file ...
