You could do what I did: ImageSize finds the width x height ยท GitHub

Then you can do things like:

require 'image_size'

=> true

x=ImageSize.of_file('/Users/rab/Pictures/Boston_MIT_8L4L2442.jpg')

=> #<ImageSize:0x32df98 @height=678, @image=#<File:/Users/rab/Pictures/Boston_MIT_8L4L2442.jpg (closed)>, @width=1024, @jpeg_dimension_segment="\377\300\000\021\b\002\246\004\000\003\001\"\000\002\021\001\003\021\001", @header="\377\330\377\340\000\020JFIF\000\001\001\001\000`\000`\000\000\377\333\000C\000\006\004\005\006\005\004\006\006\005\006\a\a\006\b\n\020\n\n\t\t\n\024\016\017\f\020\027\024\030\030\027\024\026\026\032\035%\037\032\e#\034\026\026 , #&')*)\031\037-0-(0%()(\377\333\000C\001\a\a\a\n\b\n\023\n\n\023(\032\026\032((((((((((((((((((((((((((((((((((((((((((((((((((\377\300\000\021\b\002\246\004\000\003\001\"\000\002\021\001\003\021\001\377\304", @image_type=:jpeg>

x.width

=> 1024

x.height

=> 678

x.dimensions

=> [1024, 678]

x.size

=> "1024x678"

x.content_type

=> "image/jpeg"

Well, unless you consider that an addon, of course.
