What is it?
Block upload is a simple module which allows users to upload images/files into a field without page edit. You can add this block on node pages. Choose the field you want to upload files to and set permissions. So, for example, users can add new photos into node without full node editing rights. You can also quickly add new files into node avoiding edit form.
Install module and go to Blocks management page, than find Block upload. On edit page choose file/image field you wish to use and save settings. Choose block position and here it is. Additionally set user permissions to allow uploads.
