How to Let Contributors Upload Photos in Wordpress

1. Log in to your WordPress admin area. Note that only users with administrator or higher privileges will be able to make these modifications. If you are not an administrator, ask the site owner if you can be upgraded in order to make this change, or direct them to this article so they can make the modifications themselves.
2. Click 'Plugins' from the left-hand menu bar, then click 'Add New.' Type 'Members' in the search box and press enter. When the results appear, look for the 'Members' plugin from the list, hover the mouse pointer over it, then click on the 'Install Now' link that appears. When the plugin has installed, click 'Activate Plugin.'

3. Click 'Settings' on the left-side menu bar, then click 'Members Components.' A number of check boxes will appear -- check 'Edit Roles' and 'Content Permissions,' then save your changes. This activates the features of the plugin that you need.
4. Click 'Users' from the left-side menu bar, then click 'Roles.' Click 'Administrator,' check the 'Edit Roles' check box, then save the changes. This allows Administrators to make changes to the other user roles. Now you can edit the permissions of your Contributors.
5. Click 'Contributor,' and look at the options that appear. To allow Contributors to upload images, you much check the 'upload_files' box, and save the changes. Once you have done this, your Contributors will be granted access to the Media Library, and will be able to add images to posts.
