Maximum image size for signatures

[HAU]

Basically what the title says. Giant images being used in signatures. Doesn't have to be ridiculously small but small enough to avoid seeing massive images being used.
Automatically resizing them is also a good alternative

ive been saying this for a while now, but i think 300px height should be the maximum for signatures. this includes the image + any additional text.
