How can I ensure the PNG images I download are of good resolution?

When searching for PNG images, pay attention to the file size and dimensions listed. Larger file sizes generally indicate higher resolution. Look for images that are at least 1000 pixels wide or tall for decent quality, especially if you plan to use them for larger displays. Some websites offer different resolutions of the same image, so choose the one that best suits your needs. Also, consider using image editing software to upscale lower-resolution PNGs, but be aware that this may result in a loss of quality.
