i'd recommend deleting any unwanted email you get. it's very effective.
building a site is a separate issue from receiving spam. i've built and operated several, several sites and haven't had the problem you're talkin' about. the spammers had to have gotten your email address from SOMEwhere, so, to reduce the risk of things gettin' any worse than they already may be, i'd recommend against entering your email address on any website that's questionable (which is completely your descretion).
i have two yahoo email accounts and get very, very little spam at either account. i get zero porn spam. however, i get two to five porn spams a day on my aol account (which i check about twice a month). again, if you simply delete the unwanted email, the spamming will stop. guaranteed. it may take a while, but it'll stop, nonetheless. if it DOESN'T, then there's a chance that someone may be signing you up for these mailings against your will and without your knowing. however unlikely, it still remains a possibility.
regarding the issue with netscape and your images, there's a slim-to-none chance one has anything to do with the other. you may try uninstalling netscape, checking your images, and re-installing netscape. if you're pictures are fine after uninstalling it, but get corrupted again after you re-install it, it's most likely a netscape issue and i would recommend sticking with internet explorer.
stevem.
