@sfPanzer,
What do you think the "correct" term is then? They increased the resolution, that's why the picture looks bigger. There is no other term you could use to describe this. Hell, even the scanlator themselves said that they increased the resolution, so I'm not sure what else you could be talking about.

Looks like you have a low resolution screen. In that case, you can just zoom out like you did in your example to make it easier to read. However, if you have a high resolution screen, you can't just zoom in without losing quality, so the higher resolution images look so much better now.
