What would be "foolish" about it? If you could "easily post a pix", then how does a pix of a treasure chest , or gold bar, reveal where it's located ?
Go back through the "I found a treasure" posts on T'net, and you'll see what I'm saying: Page after page, thread after thread. Persons who "found" a treasure. But upon further scrutiny, they only have a story their chasing, and have it narrowed down to a single square mile, or a certain cave, or at the bottom of a certain lake. In their mind's eyes, they've already "found" it. The dead giveaways are that they're usually "6 to 9 meters deep", and are busy at work trying to figure out how to secret it out of the country , how to assemble a crew of helpers, how to blast through solid rock, etc.... Mexico or the phillipines usually, but sure, sometimes other countries.
So please understand and don't fault those for having doubts about this song & dance "found" versus "researching" distinction. Or "saw a symbol on a rock", or "found a treasure map that I just have to follow", etc....
