What do you mean by the selection button? do you want to add icons? do you know css?

.img-metadata .ims-label {
border: none;
overflow: hidden;
padding: 5px;
text-indent: -999em;
width: 24px;
background: url("image-url.png") no-repeat 50% 50%;
}

You just have to modify/add the css file. we are woking on a premium theme but there are a few bugs that we need to fix before we release it.

@cavalini,

do don’t want to modify the plugin css. There is 2 ways in how to modify the settings and still be able to update the plugin without losing your changes.

1. you can disable the entire plugin css under settings > general and create your own stylesheet in your theme or another plugin.

2. another option is just to add additional styles to a child theme. these will override the default styles and still be able to update the theme and plugin.
