The image on the LTB forum seems to be different(smaller, different size,different exiftool result). Also this is the HTML tag of the image.

Notice the ALT description "r3ts@M" which is in reverse M@st3r (MASTER).
Not sure if data-reverse="true" is a good attribute but first time I see it.
Also the md5 sums of that image end with 7dead or dead7.
I also tried the convert to text site which was earlier posted which gave the word Miagi before and a lot of number and text were detected.
I have no idea if this related but I thought I would share.
