A little distortion is not a big problem, as long as you don't use artistic photos. If you want to upload photos, you must be confident in the sunshine and must be a standard dress photo. Life photos or art photos should be abandoned, unless you are applying for an art major. On the contrary, there is no need to upload photos at all. Except the basic information, all the contents and information on your resume must be put up only if you want to add points to the corresponding position, otherwise it should be as short as possible or not written at all.
