Say you own a terrific domain for image hosting site, what does it take to beas popular as those sites
Marketing is the hardest part - I own a photo upload site too but it's so hard getting traffic to it.
setting yourself apart from the others, not following the trends, being different and offering value and unique experience would do it I guess.
imageshack and tinypic gained popularity off of warez, bittorent sites. I remember years age, they used these sites to display screenshots and all the stuff about the warez and movies etc. So when the warez site used about 1000-2000 of TinyPic's pictures, TinyPic then bans the site and replaces all the pictures with a picture saying that this site is banned and go to tinypic for best image hosting, things like that.
