# Coppersmina
User script that enhances Coppermine galleries with direct links, color coded
border and other tiny features.
Allows the use of mass downloaders like DownThemAll! and FlashGot.
## Features
- Replace links in thumbnails to point directly to the high defintion image
- Add a colored border indicating the size of the image
- Append image information into the thumbnail's caption and remove the tooltip
- The "always run" feature allows the execution of the script even if the site
is not automatically detected as a Coppermine gallery
## Settings
At the top of the script there are some variables the user can change to
customize the script behaviour.
- Choose what information to display into the capton of the thumbnail
- Toggle the display of the colored border
- Choose if the color of the border is calculated from the image KB size or the
image dimensions
- Choose the colors to use for the border and the rages of size for each color
- Width of the colored border
- Toggle the "always run" feature
- Toggle the auto deactivation of the "always run" feature after 24 hours of the
activation
