Hi Megumi,
I'd do a slightly different approach from the previous answers. First give a name to your tab that is descriptive to the icon used, for instance ‘tab-attachment’. Then add the following to your styling:
.mx-name-tab-attachment::before {
font-family: "Glyphicons Halflings";
content: "\e142";
}
Where \e142 is the unicode reference for that icon. Use this glyphicon documentation to find the correct css rules for the icon that you want.
Try the following suggestions:

Add the icon-image to your image_collection. Then add this to your scss:
.mx-name-tabPage1::before{
content:url(..\img\yourimagefortab1.png);
}
.mx-name-tabPage2::before{
content:url(..\img\yourimagefortab2.png);
}
You probably need some extra styling-properties, but I think this will get you there.
Once you have succeeded in this little trick, can you add your solution here. Might help others, including me.
