Since it is a picture with only black and white pixels, one would assume each zero corresponds to a white pixel and each one corresponds to a black pixel.
The issue is where the line breaks are. The question has the code fit on 5 lines with 91 characters to a line and 92 characters in the last line, meaning we cannot see any obvious pattern. We simply need to adjust the width of the image until the pixels line up correctly.
We can see this with a smaller image. Both of the codes below are the same, but the different formatting distorts the image:
But when it comes to large images the 1s and 0s can be hard to make out. So to make it easier to read off, I copied the code into a text editor, replaced the 0s with the Unicode character "WHITE MEDIUM SQUARE" and the 1s with "BLACK MEDIUM SQUARE" and then adjusted the width of the text editor window until everything lined up:
So putting in the numerical values of the letters in "BRILLIANT" we get an answer of 2 18 9 12 12 9 1 14 20.
