You will often need to add "image URL" to a tool. If the tool you're using does not allow uploading, I recommend Flickr "You can get the URL of your own images on Flickr. To do this just click "Actions" and "View all sizes." You can then right-click to get the URL of the photo."
These are either free or modestly-priced website builders that allow users to create simple sites.
Pros: Full hosting and domain services are available at relatively low cost. Design is flexible. Widgets and other added functionality is available for websites. Use responsive design, which adjusts layout of pages to fit the screen size (desktop, tablet, mobile phone, etc.).
Cons: They are limited in structure. There are some bad templates out there that can result in horrible design. You are often signing away considerable rights by signing up.
These are tools primarily for giving presentations in public or on the web, but can be adapted to display a collection of items or to tell a story.
