Problems with icons.

I noticed 3 problems changing icons from Theme settings
1) the icons are much smaller
2) I lost the icons of the subcategory only the color appears
3) the page is delayed in loading

1) For problem (1) I went to style.css and just changed:

# top-cat ul li .img img {width: auto; height: 14px; max-width: 100%; margin: 23px auto; position: relative; z-index: 9;}

by
# top-cat ul li .img img {width: auto; height: 70px; max-width: 100%; margin: 1px auto; position: relative; z-index: 9;}

2) Problem (2) is shown in the attached image 15.png

Can I keep the default icons in the subcategories?

3) Problem (3) is only maintained with the new icons, it is normalized with the original icons

@iperion
Each image icon can have different size and type (can be square, circle...) therefore images are little smaller.
You can use font-awesome icons or you can use images, no combination.

Hi guys, ive just started out with this theme
Ive uploaded a few images to the icons and changed one colour, but nothing has changed. Any ideas

@aide
Back to theme settings and first read what can be configured here.

Yep done that, the only thing it says is use font awesome instead of images for categories.

Sub categories (images or colour) change does not work. Should they?

@aide
Look on configuration here, you skipped very long section.

Okay found it..
Category Icons ( TypeON OFF )
Missed it sorry.
