Hi,
you are using a really "old" version,
This (2.50) was the very first release of this branch (2.50/2.73), which was really buggy at the beginning.
Well, since version 3.x there is the question theme "image-select"
In 2.50 you can try this.
Question of type multiple with 4 columns
css class "blo"
And this css in the template.css.
[code type=css].blo input[type=checkbox] + label+div {
color: #000;
padding: 10px;
border: 1px solid #f1f1f1;
margin-left: -20px !important;
}
.blo input[type=checkbox]:checked + label+div {
color:white;
background-color: #C18D00;
font-style: normal;
padding: 10px;
border: 1px solid #0e3e63;
margin-left: -20px !important;
}
.blo input[type=checkbox]:disabled + label+div {
color: #aaa;
background-color: #EEE;
font-style: normal;
padding: 10px;
border: 1px solid #eee;
margin-left: -20px !important;
cursor: not-allowed;
}
.blo .checkbox label::before {
visibility: hidden !important;
}
.blo .checkbox label::after {
visibility: hidden !important;
}
