First, the dimensions needed...
Clan Crest - 16x12 pixels
Alliance Crest - 8x12 pixels
*All need to be saved as a 256 bmp
So make a 24x12 pixel image in photoshop/fireworks/paint. Split your image when completed. When your alliance tage matches your clan crest, it makes it look more formal.
If you run out of ideas... Do searches on objects. Make sure to search for small images so you get an idea how big it will be.
MSN Images
Google Images
Yahoo Images
AOL Images
If you can't find how to convert your image into bmp 256, save that images as a jpg/jpeg, and open it with paint. Once opened... go to File > Save As...
You will see inside Save as Type:
256 Color Bitmap (*.bmp; *.dib)
Save these files as a short name and in a easy place to import.
Example 1 (BAD):
Saved - MYFAVORITISTCRESTBMPEVER.bmp in C:/program files/lineage II/crests
When in the game, it will ask you for the location of the file. You then would have to type out:
C:/program files/lineage II/crests/MYFAVORITISTCRESTBMPEVER.bmp
And when in game it doesn't allow copy/paste.
Example 1 (Acceptable):
Saved - 1.bmp in C:/crests
When in the game, it will ask you for the location of the file. You then would have to type out:
C:/crests/1.bmp
Much easier don't you think? After you have uploaded your crest it is safe to delete the file you originally saved on your computer.
Good luck.
