我们的客户将上传图片印在他们的文件，我们一直要求拿出一个办法来获取图像的分辨率，以警告他们如果图像具有过低的分辨率，并期待pixalated在最终产品

Our clients will be uploading images to be printed on their documents and we have been asked to come up with a way to get the resolution of the image in order to warn them if the image has too low of a resolution and will look pixalated in the end-product

如果涉及到它，我们也可以去的尺寸如果有谁知道如何获得这些，但该决议将是preferred

If it comes to it we could also go with the dimensions if anyone knows how to get those but the resolution would be preferred
