how to add a 32x32 texture

[ShadowKnight95 0]

I have a weapon skin that i find really cool but it is too detailed for 16x16. it wont show if i put it in as a 32x32. also if i add a texture pack that is 32x32 it only shows the first 16 from the top left. i was wondering if there was a setting or a way to get my weapon texture in my animation.

It would help if you told us what version you are using.
