上传原图有必要,因为原图包含了完整的信息,如颜色、分辨率、细节等,对于后续的处理和编辑都非常重要。如果上传的是压缩后的图像,信息就会被丢失,影响到最终的效果。另外,原图也可以作为保留备份,以防止出现数据丢失或其他问题。因此,对于需要经常使用或处理图像的人,上传原图是非常必要的。
It is necessary to upload the original image because the original image contains complete information, such as color, resolution, details, etc., which are very important for subsequent processing and editing. If a compressed image is uploaded, the information will be lost, affecting the final effect. In addition, the original image can also be used as a backup to prevent data loss or other problems. Therefore, for those who need to use or process images frequently, uploading the original image is very necessary.
