Wireshark-users: [Wireshark-users] filter for jpeg can not use

Filter "jpeg.main_hdr.width == 640" can not use, it hints that "640 too big for this field, maxinum".
This field encodes the width of the image in 8-pixel multiples (e.g.,a width of 80 denotes an image 640 pixels wide).
If I use "jpeg.main_hdr.width == 80", it means that the number of pixels is 80, and it didn't turn out to be what I wanted (I want that the number of pixels is 640)
, it meight be a bug.
