There are 103 Travian smilies, all with transparent background (PNG files).
There are Travian 3.6 smilies and Travian 4.0 smilies, because some T3.6 smilies are better/smoother than some T4.0 smilies.
The smilies are packed in 3 categories: Travian - Outros, Travian - Tropas and Travian - Edificios. It is because by that way you can divide they into categories.
All the instructions for install they the way you like are inside the ZIP file.
