I was moving your package from gulp to webpack 4. When I started processing .scss files, I basically got stuck, because files are not found example is "InstallWizardBG.png".

.dnnWizardStepArrow {
width: 25px;
height: 46px;
background: transparent url(../../../../../../images/InstallWizardBG.png) no-repeat;
background-position: 0 -401px;
}

I am new to DNN, and not sure whether these images come from the Portal folder once you install the package under dnndev.me, or they are simply errors. Please advise. If these images come from DNN portal, then it will be hard to compile in webpack outside of the dnn environment. I am trying to work in standalone mode, before installing the package into dnndev.me site.

Please advise.

Thank you!
