These are images from CGPGrey's flickr stream.
They coudn't be uploaded with Flickr2Commons since there is HTML in the EXIF data of these images.
Some were stored in progressive JPEG format, and since the thumbnail generator was having difficulties with that earlier, I converted them to baseline.
I've got two more archives similar like this one, but only limited hosting space.
My username on Wikimedia Commons is 1Veertje.
File description txt files are included in the zip file.
