您有两个选择这种
1>建立你自己的服务器在您的PC，使其加载所有图像和图像的URI可用的，并REST API用于检索它从你的电脑的所有图像通过JSON的任何地方。这样的形象可以在你的手机中加载，可以共享，上传过任何were.For例如，你可以使用<一个href="http://stackoverflow.com/questions/20561478/using-inputstream-with-multipartentitybuilder-apache-error">this方法上载所选择的图像。
1>Build your own server in your PC such that it load all images and image URI available for it, and make REST api for it retrieve all images from your pc to any place via JSON. such that image can be loaded in your mobile, can shared, uploaded any were.For example you can use this method to upload the selected image.

使用 aFilechooser librery在您的项目，这样你可以直接选择从<一个影像/文件href="http://www.freewaregenius.com/five-ways-to-transfer-files-between-pc-and-android-wirelessly-including-some-that-youve-never-heard-of/"相对=nofollow>第三方应用（例如：ES文件浏览器），它允许您选择从您的电脑文件，并允许从您的PC上的任何文件，图像上传到你的服务器。用这种方法唯一的问题是，你必须从其他第三方应用程序查看图像，文件！如果愿意，你可以使用谷歌驱动器同步机制，同步所有图像文件夹从您的PC或使用谷歌API 。
Use aFilechooser librery in your project such that you can directly choose the image/file from the 3rd party apps (ex:ES File Explorer) which allow you to select the file from your pc and which allow to upload any file image from your pc to your server. only problem with this method is you have to view the images , files from other third party app! If want you can use google Drive sync mechanism to sync all image folder from your pc or Use Google API.
