I have a third party plugin that I'm using for a photo gallery (NextGen). However, with my black background, the loader gif animation looks pretty bad. I found a better loader gif and replaced the one from the plugin. I already know this is not ideal because the next update of the plugin will overwrite my custom gif.
The gif is located at:
Is there a clever way to leverage my child theme's
functions.php file to tell this plugin to use a different URL for the gif?
As far as using my child theme's CSS to override, that would be easiest if it was a viable option. However, the loader's URL is not coming from the plugin's CSS file.
