			let files = event.target.files;

			const myfiles = files
			let i
			for(i = 0; i < files.length; i++) {
				files[i].thumb = URL.createObjectURL(files[i])
			}
			files = Array.prototype.slice.call(files, 0)
			files = files.filter(function(file) {
				return /image/i.test(file.type)
			})
			$(".upload-iconup-logo-pic").attr("src", (files[0].thumb));
			save();
