How to upload files in joomla admin panel?

Question

PHP

Help me figure it out,
I'm trying to modify the plugin, add file uploads.
I displayed the download button, but I can not understand where the form flies when submit.
Where can I find the form handler?
***
The Noo Gallery component,
the Module simply displays images from the directory.
It is necessary to implement the loading of images in a specific directory.

Download is standard. Receiving files and uploading them to the server. Saving the link in the database. If you are looking for a component by download, have a look at cmsheaven.org/extensions/joomla/components
