Try Font Awesome’s SVG’s: https://fontawesome.com/icons?d=gallery&m=free
While there are a lot of things to like about FontAwesome, I have found that the SVG magic does not play very nicely with Angular as of FA 5.0.x. Specifically, binding classes to dynamically change icons and using structural directives such as
ngIf have not worked for me. Moving structural directives up to surrounding elements has been the only workaround I have consistently got working.
