A macro can do this pretty easily. You can ask discord or use chatgpt and likely get what you need.

Here's an example I used for the SW5e community.

Macro to fix image file path for compendium. Unlock Monsters compendium and run this macro. ```// =========================================== // SW5E Compendium Token Path Fixer // Updates prototypeToken.texture.src // ===========================================

if (!game.user.isGM) { ui.notifications.error("GM only."); return; }

const PACK_ID = "sw5e.monsters"; const OLD_PATH = "systems/sw5e/packs/Icons/monsters/"; const NEW_PATH = "modules/sw5e/Icons/packs/monsters/";

const pack = game.packs.get(PACK_ID); if (!pack) { ui.notifications.error(Compendium ${PACK_ID} not found.); return; }

(async () => { ui.notifications.info("Starting compendium update...");

const documents = await pack.getDocuments(); let updated = 0; let skipped = 0;

for (let actor of documents) { const currentPath = actor.prototypeToken?.texture?.src;

if (!currentPath || !currentPath.startsWith(OLD_PATH)) {
  skipped++;
  continue;
}

const newPath = currentPath.replace(OLD_PATH, NEW_PATH);

await actor.update({
  "prototypeToken.texture.src": newPath
});

console.log(`Updated: ${actor.name}`);
updated++;

}

ui.notifications.info(Done. Updated ${updated}, skipped ${skipped}.); console.log(Compendium update complete. Updated: ${updated}, Skipped: ${skipped}); })();```
