This mod adds the theme pictures as thumbnails to the gift voucher page in the front end.
The thumbnails are placed in a grid rather than all in a long column.
The size of the grid and the thumbnails can easily be altered in the xml file; instructions at the top of the file.
The mod only works with the default theme and themes that have an 'account/voucher.tpl'-file that is structured like the default one.

The mod requires vQmod and is tested using vQmod 2.5.1 and Opencart 1.5.6.4/default theme.

There are two versions: one for OC 1.5.4.x - 1.5.6.x and another for OC 2.0.0.0
