You should be able to remove bullet points through via CSS using:
ul { list-style:none; }
This will remove the bullet point for all unordered lists, including nested lists. To target a more specific area (eg. the projection output on a projection page) you could use:
.projection-page ul { list-style:none; }
If you are using a projection widget, and say you named it 'pictures', then you could use:
.widget-pictures ul { list-style:none; }
