ListHD Basic allows users to upload images by emailing them in as attachments, which is convenient since most people are very familiar with emailing on their smartphone.
While the email is being processed, users enter a title and description, then hit save. Most likely, images will have uploaded and will show up by then, but if not, just wait a minute and Save again.
Once the images show up, users can select a template and preview it. The code for each template is shown at the bottom and can be copied and pasted anywhere.
