I want to take data from my own plugin settings page. Could it possible? I found this: In table "system_settings" locates my data. In table "system_files" locates names of image, what i put into my form on settings page. How it merge?

Sorry for my bad English.

You can do something like this:

use path\to\your\settings as YourSettings;

YourSettings::get('setting_you_want');
