Incorrect images

Hello, i have noticed that a few images are incorrect, the first one being the IS-3, there is an image of an IS-2, IS-3 hase pike nose hull armor and a low rounded turret, the second one is ISU-152, the image there is of an SU-152, ISU-152 had increased armor and a DShka mg on top, next one is the spg S-51, it has an image of an SU-152, the S-51 had the 203mm B-4 howitzer, is open top and is longer, another thing i noticed is the BT-7 and KV-1b being in the medium tank line, BT-7 is a light tank and KV-1b was a captured tank, but it was still a heavy tank, my suggestion is to put A-32 instead of the BT-7 and an T-34-57 instead of the KV-1b and then there is the ISU-122 but im not sure if its a error or not but it looks similar to the SU-122-54, anyways thats all i could find, i hope im not wrong about these
