How to specify the size of bank campus recruitment photos?

Online registration for the bank recruitment examination requires candidates to upload photos of their ID cards. The photo size varies according to different banks. ICBC requires the photos to be within 30K, in jpeg/gif/jpg format, and the size is 100* 140. The Bank of Communications requested a recent one-inch bareheaded photo. 1 inch photo size refers to 2.5*3.5cm

Another factor that affects the quality of a photo is the pixel of the picture, which is usually called the resolution, which is an important index to reflect the photo file. The higher the resolution of the picture, the larger the pixels per inch per unit area, and the picture.

The clearer and more delicate; On the other hand, if the pixels of the picture are not high enough, the printed photos may be blurred and the colors are not bright enough, which is very likely to cause some distortion.
