Yes the pictures showed when I clicked on the link.
Skin depth varies depending on frequency and how conductive the material is.
Proximity effects are something else, not sure they are related. Usually in RF circuits you would not place anything within a distance equal to the coil diameter to minimise reduction in the Q of the coil, I.e. An increase in its losses.
I hope this helps,

Actually they are related, in that skin effect is the result of eddy currents generated by a conductor's own AC magnetic field, while proximity effect is the result of eddy currents generated by the AC magnetic field of adjacent conductors.

That was a good explanation, thanks for that.
