The photon mass math is trivial.

E= mc^2 = hf

m = hf/c^2 = h/(c)lamda

If I remember correctly, a photon cannot travel slower
than the speed of light.

Are you proposing that a photon cannot travel slower than the speed of
light in a vacuum, or it cannot travel slower than the speed of light
in water or the speed of light through glass or air? Please reference
which speed of light a photon cannot travel slower than. Assuming your
answer is the universal constrant "c", then my question is, knowing
that light travels faster through a vacuum than it does through water,
is the light travelling through water still "photons" or is that
impossible because they are travelling too slow? What are they then?
Please advise. Thanks.
