const layers = figma.currentPage.findAll(isImage);
figma.currentPage.selection = layers

for (let shape of await find(selection(), n => isImage(n) && n)) {
// Update image paints to use "FILL" scale mode
  shape.fills = shape.fills.map(p =>
  isImage(p) ? {...p, scaleMode: "FILL",} : p)
  shape.resize(375, 375)
}
