Assigning new fonts in OS X for PS 7.0--URGENT!!!

I unstuffed a zip file with new fonts I'd like to use in Photoshop 7 on my Mac. However, other than the ones that are already on the fonts list in PS, I do not know how to use the new ones I downloaded. I tried dragging and dropping them (after unstuffing them) into various "fonts" folders on the Mac HD (even in the various "Adobe Application Support-->Fonts" folders), but... nothing. I do not have Extensis Suitcase on my computer either. My friend does, and apparently, he gets PS 7 to recognize the fonts just fine. Is there any other way to get PS 7 to recognize these new fonts w/o the need for Extensis!?!? I have a PSD file in dire need of these new fonts that I can only use on the Mac, seeing as though all my editing software is Mac-only (but the PSD was created on PC). Please help. This is VERY urgent!!!

[[[[Using--Mac G4, DP 1 Ghz, 1 GB RAM, OS 10.2.5, with PS 7.0 (Ed version)]]]]

Thanks in advance.

Restarted and nothing worked. Even Boris FX doesn't recognize them. UGH!!!
