I want to post some images that I do not want downloadable via right click or whatever.  How can I do that?

Here we go again.  In my years on the site I have been in the exact same question several hundred times.  The definitive answer is:

The only way to prevent someone from taking your images is to not put them on the Internet.  There is no way; repeat no way to stop the user from taking them. In order for the browser to display them, it downloads them to the users computer.  

They don't have to take them, they just have to keep them.

I'm going to quote Cd& this time:

Now you may see things like disabling the right-click Context Menu.  Don't bother, it is trivial to get around that.  If you put it on a web page, I can copy it.  There is nothing you can do to stop me.

So you can't place them behind a transparent div with a watermark or use some other sleight of hand?  I understand that it is not going to fool you or many people that use this site but isn't there some way to prevent the vast majority of human beings from getting at them?

Stopping someone from getting them on the screen is nothing but nonsense.  Do you think the average user does not know how to do a print screen?

Plus what is on the screen is nothing, The image is already on the user hard drive.

Can you make it harder? Sure; just make the page less usable; less SEO fiendly and the only ones willing to use the page will be the ones who know how to defeat you.  If you rely on the site to generate revenue, then every measure you attempt will not only fail, it will reduce your return traffic because you will have to attack your user and violate their rights.

BTW:

Even total newbies know how to save a page. and when they do that the images are saved automatically as part of the folder with everything else.

Ok I get it.  I gotta say that I love this site because I have never been made to feel like a dumba$$ until this post.  I am a teacher by day (so I know about questions that seem a little bit elementary) and  a self-taught web guy.  My background has a ton of holes in it.  We have just found one.  I pay a monthly fee to use this site and it is money well spent but if I had a lot of responses like this one I would cancel my account.  I just hope that, like email and other electronic communication tools, what might seem like rude and condescending is something less significant.

I do appreciate the insight that I have gained from this post so I am glad I posted it.

Well at least using this site you are being told the truth - plain and simple.  The same question is asked continually by people (so don't think of yourself as the exception more the norm) and they usually get the stupid answers like use this software, do this blah blah blah.

The second most common version of this question is about PDF files.  But the answer is the same.  If I can read it, I can copy it.  The only files that can't be copied are those that run on the server like PHP, ASP, ASP.NET.  Those will generate HTML that shows in the browser but the language code never leaves the server.

I'm not sure which comments you found offensive.  None of them them were intended to do anything but anticipate the normal followups; save you some time; and discourage post from what are known a Google Monkeys who are quite happy to chase you around looking at links that propose a lot of non-solutions.

Sorry if you were offended, but what you got was straight correct information.

It was the comments like "Here we go again." ,"...nothing but nonsense.  Do u think the average use...". Again, may not have been as "rude" as I thought but certainly a little curt or condescending sounding.  I have used this site for many years and I plant to keep doing so.  As well, I hope all experts that assisted me on this do so again in the future.  It was just that this thread seems a little unlike EE.  I do, however, appreciate the factual nature of the responses.  Thanks again.

I'm afraid we were anticipating the extended arguments that have happened so often.  Sorry.

Just keep the image as low in resolution as possible and put on as many watermark as you can without detracting from the image.

Have a look at the photos on ebay shops ... you will find many faint watermarks going diagonally from one corner to the other.

You could also make life more difficult for would-be thieves by 'slicing' the photos in photoshop into multiple bits. I'm not sure on this, but I think they would have to reassemble all the bits to get the full image.

Meanwhile while you have spent half your life slicing images and the other half getting them to fit together properly and wondering where that white border has come from I have spent 2 minutes putting them back together in photoshop

Dave BaldwinFixer of ProblemsCommented:
I would do a screen capture of the sliced image... since it would be whole on the screen and crop it to the part I wanted.

EirmanChief Operations ManagerCommented:
Surely a screen capture is never as good as a 'Save Image As'

I've used Screenhunter 6 to capture a specified region of a screen to a file with one keypress and I still prefer save as



If slicing was a dumb suggestion, I'll bow to the greater wisdom here.

Not so much dumb as a waste of time.
For the time you spent on it and the time to circumvent it - there are better things to be doing in life like SEO on your site.

I actually copied a sliced image from Hustler mag.. and printed it on a t-shirt! ;-)

Dave BaldwinFixer of ProblemsCommented:
If the image is the exact size as the original, a screen capture IS, for all purposes, the original.

@BobbaBuoy,

Let me tell you why you got responses in the form you did.  Most Experts look at profiles to try and get some idea of the best way to deliver information.  That is particularly true when the response is not what the questioner wants.

Look at your profile.  What information is there.  Are you a college kid doing your first web site; a business owner trying to save a few bucks by doing their own web site;  a professional developer branching out to web development?

The nature of the question and the lack of information leaves the impression of someone with no idea about how things work on the internet; and we are about to do a dance we have done a hundred times before eliminating all the stuff that won't work; all the stuff that will limit accessibility; and in the end the questioner is going to be upset because all we did was waste three days of their time posting nothing but negative answers.

I also spent time teaching at Community college and I still do the occasional guest lecture at Universities. When a topic comes up that is a dead end, the best way to deal with it is just jump to the end and get on to something more productive.

As I said, there was no intent to be offensive; I was just trying to save us both some time.
