Yes, there is some requirements before you can upload your very own picture. Which are:

" Pictures for cat units in battle, squared, and cleared from intrusive elements (cats, enemies, base, HP, God Cat)." Also, pictures needs to have  a matching background.

So first of all, you will need a cropping tool.

(This probably sounds quite difficult, but it's really not that hard...)
