Jared Fogle -- Subway Orders All Signs Down, With a Catch ...

Jared Fogle is the invisible man at Subway -- and not because he's losing weight -- his image is quickly being removed from shops across the country ... but he's not going far.

TMZ spoke with a slew of Subway stores ... and we're told word came down from corporate to take down or cover up ALL signs of the now suspended pitchman -- after his home was raided Tuesday as part of a child porn investigation.

What's interesting though ... we're told store owners were instructed to hold on to all Jared promo materials -- just keep them out of sight in the back, "until someone says otherwise."

We did speak with one store who said their manager said toss the Jared stuff in the trash. Obviously, not everyone's expecting a comeback.
