Hello @reamianv,

Which version of ProtocolLib are you using?

[reamianv]

What I tested with ProtocolLib was:

Observed results with Purpur 1.20.1 + Packet Event + protocollib
Yamipa 1.3.2 / ProtocolLib 5.3.0 version.

The image is present, but it isn’t visible, so I downgraded Yamipa back to the previously working ProtocolLib 5.0.0, but the image still does not display. I also created a backup, placed the image in the appropriate location, and received a message saying the image was created, yet it still doesn't show up. I repeated this process with ProtocolLib 5.3.0.

Afterward, I reverted to Yamipa 1.3.2 beta and ProtocolLib 5.0.0.
