How to reuse jstree image asset outside the tree itself

[SageGary]

I am using jstree in an ASP.NET Razor page. On the same page - outside the jstree itself - I also sometimes need to display a spinner gif when some long running action is happening, and to keep the UI consistent I prefer to reuse the throbber.gif that is part of the jstree assets. The following seems to be the most straightforward way to me, is there any reason not to do this, or should it be ok?
