本系统主要从现代社会电脑化观念出发，通过对现有资料的分析、研究和整理，确定了在基于现存的WEB2.0模式下开发图片共享系统的可行性、紧迫性和必要性。在现阶段,国内基于WEB2.0的图片共享系统才刚起步,该市场还有很大的介入空间。其中，在国外，已经有了很成熟的图片共享平台。在WEB2.0时代，信息由以前的服务器发布变成了用户发布。也就是从以前的通过服务器搜集资源并且发布变成了通过用户提供资源，服务器进行整理，分类，发布的模式。而且这种模式对于一个网站的用户吸引度也远远高于传统模式。

本论文旨在详细说明如何在基于PHP以及Ajax框架的环境下，使用MVC的开发模式，完成一个具有完整功能的图片上传以及图片管理系统，并能够实现方便的添加，删除图片以及分类，后台主要实现对用户以及用户的图片进行管理；能实现相关个人的设置更改。并且系统中对于图片上传需要有比较直观的进度显示，图片的呈现使用比较友善的显示效果。

This system mainly embarks from the modern society computerization. Based on existence information analysis, the research and the reorganization, we considered the pressing and the necessity of implementing order form developing picture share system base on WEB2.0.At the present stage, the domestic picture share system based on WEB2.0 is just underway.  There is expansive to take part in this field, at the same time, mature picture share system aboard is already exist for a long time. In WEB2.0 period, the style of information publishing turned from server publishing to user publishing .In another word, it is changed from server publishing information to user providing information, and in this case, servers only need to coordinating, sorting and republishing. Furthermore, in this model, a website is much friendlier to user.

This thesis mainly describes how to developing fully functional pictures upload and picture management system. This system can easy to add, delete pictures and categories. In the backstage management, is mainly to implementing user and pictures management and user information changing. In this system, picture uploading is intuitionisticly showing, and the picture is need to be shown user friendly.

 

Key words: MVC; Picture Share; Ajax
