Using a single 6K texture at only **227kb** in size, spikes the memory usage to a crazy **144mb** of memory in Blender.

It was brought up in [this bug report][1], but closed.

Why can image editors (Photoshop/Gimp/Krita) handle such large images but not Blender?

Whats going on, and more importantly, what can be done to improve it?
