Let's start first in creating an Emblem for your guild.
To Create an Emblem:
1. Find an image you’d like to use.
2. Save the image on your computer (Desktop, My Pictures, etc)
3. For PC, Right click on the file, and go to EDIT.
4. Paint will pop up. Go to IMAGE tab in the menu, and click on STRETCH.
5. Stretch or Shrink the image until you reach the desired 24×24 pixels. If the pixels are too big, you shrink by putting in less than 100% for stretching. You can check the pixels by going to IMAGE tab again and clicking on ATTRIBUTES.
6. Re-save the file as a 256-bit (bmp) file.

Second, how to add a Guild Emblem in RO.
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 24×24 pixel Bitmap (.bmp) 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 RO file directory is C:\Program Files\Gravity\RO.
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.
