Description

Simple Family Photos is a web interface designed for uploading and grouping
photographs into events. These events can be shared among family and friends,
and provide a logical structure for searching and viewing photos. The site is
intended to solve the issues that arise when many family members take
photographs at an event and have no easy way to aggregate and share them.
Simple Family Photos will provide central storage and a simple way to upload
and view these event photographs for anyone in the family.

The site is intended to be used by families. That being said, most families will
consist of people with widely varying technological skill sets. Simple Family
Photos will be tailored so that all of the members will be able to contribute and
add/view pictures. With this user base in mind, one of the benefits of Simple
Family Photos will be lowered complexity for the photo sharing process. The site
will be simple to use, and faster than trying to send photos through email, share
them on digital media, or send links to individual photo albums. Another benefit
will be time savings. The aggregate nature of the site will speed up the event
photo sharing process—each member will upload their photos once, without
worrying about distributing them to every other family member.

Some alternatives that exist for viewing and sharing photos include Facebook,
Photobucket, Picasa, and Flickr. While being very powerful, these websites are
designed with technologically savvy users in mind; they are not always simple for
the average person to use. Additionally, these sites tend to group photographs
together by user. This method is sufficient for the purpose of maintaining user
pages and searching for arbitrary pictures, but would leave much to be desired
as photo storage for an event.

In contrast to these systems, Simple Family Photos will focus on being easy to
use for anyone, regardless of technological skill, while also providing a means to
collect photos from multiple family members into a single event album. This
difference should be clear to any user who’s tried using other photo-sharing
systems: the simplicity of group sharing will be much more obvious compared to
the single-user alternatives.

We expect at least two very different levels of documentation this will require. At
a basic level, most users will need to understand how to operate the basics:
uploading pictures and organizing them into events, as well as searching for
specific event albums. This will require a system for providing simple help about
these processes to new users, as well as reference animations, which can be
used to demonstrate simple procedures.
The more advanced level of documentation will apply for family administrators,
who are assumed to have a greater technological grasp. The admin
documentation would need to be more detailed to account for greater control
complexity. While some tasks could be demonstrated in a manner similar to the
basic level of documentation, others would require more explanation, likely in the
form of help files and tool-tips.


Scope

Simple Family Photos’ focus is to support photo albums of family-based events.
We are not aiming to provide a feature-laden general service for publishing
photos or a site that will cater to the social networking set; we want to replicate
the family photo album sharing experience. This will keep the site simple and
easy to use for less technologically skilled users.

The site will also not be a guaranteed backup service. The service will store
photos on a central server (and will likely be backed up regularly) but it will make
no guarantees about reliability. It will be made clear to users that they should not
upload pictures to the site and then delete local copies.

Simple Family Photos will be web-based. As long as a user is running a device
with a web browser, he or she should be able to view and upload photographs to
family events. This keeps the site simple and accessible. We may use HTML 5
for some features (e.g., multiple uploads), with a graceful fallback to HTML 4.01
for users who are not using up-to-date web browsers.

Internally, we will be running an Apache web server on Cubist. We will also be
using Cubist for our database storage (MySQL or PostgreSQL).

Performance is an important factor in any photo sharing website. The storage
database behind Simple Family Photos must be quick when searching, browsing,
and downloading pictures. The front-end itself must always be quick to respond,
without major delays in user control.
