Out of pure boredom i wrote a small script to download all gifs from that square above the board name. As i quickly found out all of them are ordered in a https://s.4cdn.org/image/title/${some number} .gif
As i found out there were 253 of them, unless there are some more above the 300 number.
But for some reason some of them are missing. Quite a lot actually.

Anyone knows the reason? Did they got deleted? Also, are there any autist like me who did the same thing previously? Do you have any of the missing images? If you do, please post them
