    Try this. You can replace default radio/checkbox by removing the default style first, then apply pseudo element as shown in the snippet.
PS: For this, Use font-awesome library
.checkbox-custom, .radio-custom {
    opacity: 0;
    position: absolute;   
}
.checkbox-custom, .checkbox-custom-label, .radio-custom, .radio-custom-label {
    display: inline-block;
    vertical-align: middle;
    margin: 5px;
    cursor: pointer;
}
.checkbox-custom-label, .radio-custom-label {
    position: relative;
}
.checkbox-custom + .checkbox-custom-label:before, .radio-custom + .radio-custom-label:before {
    content: '';
    background: #fff;
    border: 2px solid #ddd;
    display: inline-block;
    vertical-align: middle;
    width: 20px;
    height: 20px;
    padding: 2px;
    margin-right: 10px;
    text-align: center;
}
.checkbox-custom:checked + .checkbox-custom-label:before {
    content: "\f00c";
    font-family: 'FontAwesome';
    background: rebeccapurple;
    color: #fff;
}
.radio-custom + .radio-custom-label:before {
    border-radius: 50%;
}
.radio-custom:checked + .radio-custom-label:before {
    content: "\f00c";
    font-family: 'FontAwesome';
    color: #bbb;
}
.checkbox-custom:focus + .checkbox-custom-label, .radio-custom:focus + .radio-custom-label {
  outline: 1px solid #ddd; /* focus style */

    You should use css changing the element next to the checkbox.
In this example it's the background color. Just replace it with your images.
For example: https://css-tricks.com/the-checkbox-hack/
input[type=checkbox] {
   visibility: hidden;
   /* For mobile, it's typically better to position checkbox on top of clickable
      area and turn opacity to 0 instead. */
}
/* Default State */
label {
   background: green;
   width: 400px;
   height: 100px;
   line-height: 100px;
   color: white;
   text-align: center;
}
/* Toggled State */
input[type=checkbox]:checked ~ label {
   background: red;
}<input type="checkbox" id="toggle-1">
<label for="toggle-1">Do Something</label>
