Sorry, still a little confused. I'm not an idiot, just not familiar with the procedure..(publically acces. site?? Example??)
I have several examples. Sometimes your ISP will give you some disk space for a personal web page, and you can upload files to there. And there are "free web" sites around, like
Tripod or
Geocities or
Angelfire or
Freeservers where you can sign up for free disk space on their web servers and it won't cost you any money. You don't get much -- just a few megabytes, but that's more than enough for a few JPGs.
Be aware that some of these places will try to sell you a domain, or web hosting services, but that's not what you want. If something asks you for a credit card number, back out and try again.
