Just create a new PrivateAsset and return it
public IAssert getAssert(int percentComplete) {
IResourceResolver = getPage().getEngine().getResourceResolver();
ClasspathResourceLocation imageFolder
= new ClasspathResourceLocation(resolver, "path to images");
return new
PrivateAsset(imageFolder.getRelativeResource(String.valueOf(percentComplete)+"/gif"));
}
not the most efficent example but you should get the idea.
