Drop .gif, .png or .jpg files in this folder and a hologram line of
<gif:filename> will show that picture as a billboard in the world.

The file itself is streamed to each player when they join and held in memory only, so keep
the folder small: one file is capped at 8 MB and the whole folder at 24 MB. Animations are
capped at 120 frames. How big the picture is drawn is a per hologram setting,
not a property of the file: use /hologram size <name> <blocks wide>.

Run /hologram reloadgifs after changing anything in here.
