Q: How do I set my guild's emblem?
A: Only Guild Leaders can choose and implement Guild Emblems. To put implement a Guild Emblem use the following procedure:
1. Make sure that the image file intended to be used as the Guild Emblem is 24x24 pixel Bitmap format file in at 256 colors (8bit).
NOTE: The transparency color for guild emblems has the RGB values (255, 0, 255), or you may use the hex value #FF00FF.
2. Create a directory named "emblem" in the RagnarokOnline file directory. By default, the RagnarokOnline file directory is C:\Program Files\Gravity\RagnarokOnline.
3. Copy or Move the Guild Emblem bitmap file to the emblem directory you have just created.
4. Log into the Ragnarok Online game and open the Guild menu (Alt+G) and click on the `EDIT` button. If you have done all the steps correctly, the name of your Guild Emblem file should be available in the Drop-Down Menu, select it and it will be set as your Guild's emblem.
