To change the footer image, you need to place an image in the <strong>webapps\share\components\images </strong> folder. The file name should be logo.png.
Please let me know, if you need more help on this.
thank you I ended up commenting the snap section on the footer.get.html.ftl and that hided it, ther's also a solution by integrating a jar(fme-hide-footer-0.1.jar) but the commenting way did the job, thanks
