I'm already aware that some signature limits exist, but I feel like some more are needed.
I agree that signatures should allow us to use some pictures and gifs, but I feel like some signatures are just too big, taking too much space on topics, because of multiple pictures, may they be big or small.
I mean, some signatures take 200-300% more space, than the actual reply itself!
I think that setting some limits could be a way to go, may it be max file size, or pixels per pixels, it could save lots of space, and allow more replies per page while on a topic.
Current Limits; Max characters: 550; Images in your signature must be no higher than 420 pixels
Edit: I just took a moment to examine the current limits, image limitation by pixels do exist, but perhaps it is still too large, as we can clearly see 2-3 big images in a single signature, one bellow each other, making it even "bigger".
