Is it illegal to add a hyperlink to someone's website without their permission?

It is completely legal to add a hyperlink without their knowledge. \n\nIn fact, they would probably encourage it as it can only increase traffic and web-bot traversability.

Remember!\n each thing on a website is copyrighted even if the webmaster / owner has not put a copyright notice.\n to copy / save any item from a website u must have permission to do that. to get permission send an e mail to author of the website and ask for permission.and if he alows u to copy/save the data from his site than u can do.\n and if u do not recieve any reply from the author dont consider thats mean is ok to use.\n any way. many webmasters do not care  or they allow people to use thier data.but its better for u too contact to them before using thier data.

I think this is called "hot-linking" and most of the public servers doesn't allow this.\nJust imagine i build a page (my_domain.com/subdir/frame1.html) that loads your page (domain.com/subdir/page1.asp) into my frame. Man! it's your page, and I'm stealing not only your content, but also your bandwidth.\nThat's the reason why it's not allowed.

Put http://www.yoursite.com/myreference.html instead of just www.yoursite.com/myreference.html\nor try <a href="www.yoursite.com/myreference.html">my reference</a>

Whether it's graphics or information, you should first read over the site carefully for copywrite information.  Many sites have copywrites on their graphics that forbid others to use them without express permission.\n\nIf they don't have any copywrite's, you can use them but as a courtesy, you should send the owner a note requesting the use of their graphics.  This will also cover you because if they put up a stink or try to charge you, then most likely if they ever found out you were using their graphics without asking them, they could try to take action against you.

There is some outrageously bad advice above. \n\nYou unquestionably violate the copyright of the photographer when you reprint it without authorization, regardless of the fact that it's on a web page. Further, you violate the copyright of the web page author.\n\nThe only exception to the rule is what's known under the copyright law as a fair use...  and what you've described is unlikely to qualify.

Its not like if you go to a site with them you get arrested. You would have to go through many steps to download it, and even then you would still have to actually file share. I think you're safe.

Don't be a prude . . . but the decision is yours . . . in yahoo . . . there is usually a local abuse button.\n\nMeanwhile, can you add them as a link with your additional information . . . I want to take a look . . .

The internet is still such a recent phenomenon, that laws and policies are being created as we speak.\n\nBut unless you're pretty certain they'll be OK with it, you should ask someone if you can put a link to their website on your blog. That would  be the right thing to do from an ethical standpoint as well.\n\nA lot of people create 'banners' for other people to put on their websites as a link to their's. But some people don't mind if you put the URL.\n\nBottom line is, when in doubt check it out. I can't answer your question about the legal ramifications (see link, below). But my bet is that you could end up getting into some hot water with someone if they haven't given you permission prior to your adding the link. Why risk it? It's just a matter of asking.

If you do not want someone to use something you write keep it private.  If they are using something you've written and not attributing it to you, this is a violation of your copyright and I imagine you could send a takedown notice.  I really don't think you want to do that, however, that is the mechanism that websites use to control the misuse of their intellectual property.

Yes, it would be illegal without their permission.\n\nYou need to contact their corporate offices and tell them what you want. They will either tell you no, or they will charge  you a licensing fee that authorizes you to use the images.

No. They only use the information for their use.  It is against the law to give that information to anyone else because you have not signed a consent.

Yes, it would be very easy to make a case for violation of copyright for you using someone else's picture without permission. Quite a few people won't pursue it, but it is an option.\nThe best way is to email the webmaster (or copyright holder) for permission to use it; if you get the permission save the picture to your own server (so you aren't stealing their bandwidth), and then link using the img tag. To give proper credit, you should probably include a copyright statement, either as a caption near the picture, or in the title attribute of the img tag, like...\n<img src="pic.jpg" title="Copyright © (date), (copyright holder's name and website), Used with permission">

not sure of any exact laws but as long as you are not lying about something or plagiarizing you should be fine, also if you are posting adult stuff i think you have to have a pass word thing set up to make sure kids are not getting on to it

Yes, in some cases, people can create a false web page...like a "screen shot" of say, a Citi Bank website, and they will put in a link that will take you to their site where they can obtain all your information.  This is not uncommon, but it is as simple as typing in yaho.com instead of yahoo.com (they buy up close domain names)

Maybe you're not including the http://www. when you type in the link.
