Hi,

Could you please give us more details? What are you doing exactly and where the upload link was before? Could you be more specific please?
Are you editing some document on the Form tab or where you want to select and upload the image?
You can also create the image as a new document (CMS.File) e.g. under some folder (http://www.kentico.com/docs/devguide/file_management.htm). And you can also upload new image when using Image selection form control for certain document type.

Thank you in advance.

Best Regards,
Juraj Ondrus
