Problem with image cache at mysqueezebox.com for Linn classical radio

Hi, I listen to Linn classical radio and am using mysqueezebox.com to resize artwork.
This works fine for most playlists, albums and radio stations, butb the Linn classical radio icom looks very weird when resized this way.

Compare

with the original

Rsizing locally solves this, but I really prefer to offload all this to the mysqueezebox service since it's there.

Can anything be done from our side to trigger a rescan?
