It's gotta have garlic!!! Anyway, sounds like your Photoshop gamut settings have been screwed, or changed. If this didn't used to be a problem, what changed (update Photoshop, update OS, delete a user's settings - could you be viewing in CMYK preview) Aside from that, I've noticed that images I save for the web are considerably lighter than images opened in Photoshop - but i have my system calibrated for publication, which looks much darker than web images...?
