The problem is not that they are small,
It is that they have a poor resolution so zooming only gives blur.

Seems all right to me

Think so.
The most easier for them would be to use \exp instead of e^{},
but imho the image tag should have an "alt" parameter with the formula in LaTeX (or whatever)
that usually shows up when the mouse pointer is on the picture.
