Hello! I have the following Apex Class that is designed to allow attachments to upload via a VF page. I know I have to be missing something really obvious, but I can't get the VF page to show up in my Page Layout so that I can deploy it to users. The VF page should appear on the custom object "Install_Note__c". Any ideas?

- - - - -  

public class AttachmentUploadController {

  public Attachment attachment {
  get {
      if (attachment == null)
        attachment = new Attachment();
      return attachment;
    }
  set;
  }

  public PageReference upload() {

    attachment.OwnerId = UserInfo.getUserId();
    attachment.ParentId = '01I700000007zWH'; // the record the file is attached to
    attachment.IsPrivate = true;

    try {
      insert attachment;
    } catch (DMLException e) {
      ApexPages.addMessage(new ApexPages.message(ApexPages.severity.ERROR,'Error uploading attachment'));
      return null;
    } finally {
      attachment = new Attachment();
    }

    ApexPages.addMessage(new ApexPages.message(ApexPages.severity.INFO,'Attachment uploaded successfully'));
    return null;
  }

}

And then this is the VF Page:

<apex:page controller="AttachmentUploadController">
  <apex:sectionHeader title="Visualforce Example" subtitle="Install Note Photos"/>

  <apex:form enctype="multipart/form-data">
