Hi, how do I update the icons for this theme?

@kirshbaku
Go to theme settings and at bottom upload your own icons.

That's exactly what I tried, but the icons are not showing.  Tried several browsers and cleared the cache. 

@kirshbaku
If you uploaded images, you need to change font-awesome icons to images, again in theme settings.

@ frosticek
if i upload images, why couldn't displaying full circle of picture ? 

@shan5500
Because it does not.

@frosticek
Sorry again, I couldn't understand your answer properly.
My Question is,

The categories icon/images wanna show bigger then default size which provided by theme. because icon/images cannot see clearly..
Please refer attachment.
