title: insert an image in kentico cms
body: <p>I use Kentico CMS v5.5.3996 R2. I have a custom table with a column with below characteristics:
  Attribute type: "Text" 
  Field type :"image selection"
  I have created an alternative form for this table (for insert) and show it in live site. My problem is that this "Image selection" shows all the images in kentico (It's good for administrator but not for users). Is there any other Field type for this purpose? (like avatar selector)</p>
  
  <p>(Of course I decided to create a handy form (web user control) for insert, but my new problem is that " how to save image in kentico?"</p>
