Epsom salts are otherwise known as:

Magnesium sulfate heptahydrate

MgSO4 7H2O

but I can't seem to find a picture of the crystal structure anywhere...

As regards the crystal structure, it is a polymorph!

That means that the hepthydrate form of Magnesium sulphate can be an
orthorhombic crystal with a 2,2,2 symmetry (it is disphenoidal, and
that's rare). It also can be a monoclinic just like hydrated iron
sulphate.

For reference go to either of these pages. Images on the second one.
