When I use image3 addon to read a large jpeg, it raise a memory limit error, (I lower the memory limit to avoid swap). So I use 7!:5 to measure the space in bytes used by the named objects,

   B=: 100 200 3$2
   7!:5 <'B'
262144
   */4 100 200 3
240000
   B=: 1000 2000 3$2
   7!:5 <'B'
33554432
   */4 1000 2000 3
24000000
   B=: 2848 4288 3$2
   7!:5 <'B'
268435456
   */4 2848 4288 3
146546688

It requires nearly double amount of space for large object. Can this be 
improved?
