在为应用广告系列制作图片素材资源时，应该考虑以下哪两项？（请选择两项。）

Using actual in-app footage creates more engaging creatives because it directly showcases the app's value and user experience, which is highly effective for app install campaigns. Images with high pixel density ensure clarity across various screen sizes, preventing pixelation and maintaining a professional appearance, which is crucial for a positive user impression. Overlapping logos and excessive text can clutter the image and make it less appealing, potentially violating ad policies. A "Learn More" call-to-action button is typically part of the ad format itself, not an element to be embedded within the image asset.
