    picked the Wallpaper template for this course because it takes simple
    images as content, and there’s plenty of images on the web that you
    can use.
    We will not go over the methods of finding or creating content for your
    apps in this course, you can visit the academy later on for that.
    Instead, here’s a list of specific URLs where you can find ton of images
    to use as content, for each niche.

    use )

    use )
  • Tattoo Designs : Get them from Pixabay ( Free for commercial use )Based on the niche you picked, go into the provided links above and

    To add content to your app, follow the steps below :
  • On AppyGEN, click the Content button next to your new app
    project, and then click on Add/Edit Content.

    the Image URL field
