All My Blank Tracking Pixels

BlankEmailPixels-700px

Emails often contain 1×1-pixel, transparent, or tiny hidden images used to track that the email has been opened. Using a Python script, I gathered all 12,383 of them in my inbox and deleted mail folder into the image above. The black pixels on the bottom are the remainder of the pixels in the final row.

The above version is scaled up; see the pixel-accurate 111x112px version here.
