Cannot change the icon on a Child Theme

Good evening. I´m creating a website with your Full Frame Theme but i got a problem when i sent it online for testing. I have inserted a logotype at the top of the site, at the left of the menu, as you can see below. http://varalstudio.com.br/icon_option.png I have inserted this icon using a child theme, but when i uploaded this site for testing, the icon becomes broken. Another printscreen below. http://varalstudio.com.br/icon_option_not_ok.png I know that this logo is not appearing because it is linked with my personal localhost but i can´t insert a new one. If you please take another look at both print screens you may see that in one that represents the original theme there´s the Icon Option on the left menu but on the child theme there´s no such option. Any idea? Thank in advance and sorry if i didn´t make myself so clear, I quite rusty with english. Fábio
