how do i show a pic to someone? JUST SHOW!!

[solidsnake]

umm so here's the deal. i need to show a picture file to someone . but i have to make it like this . so he/she is not able to save it at all.  get the point. like he/she can only open it once or something. like that

please suggest

thank you

[disturbed]

sorry bud, not possible - even with tightest scripts its not possible - person can always take a screenshot of the screen and get the picture that way

[solidsnake]

ofcourse ofcourse. ok so let me rephrase it. the person is not that advanced to screenshot it.

all he/she can do is save or something . thats it.

any kinda help will be helpful . thanksa

Are you talking about hosting it? Or sending it to them?

[solidsnake]

Sending . or anything , putting up on net or anything. i wanna show it to them ONLY momentarily.

There has to be a way to do this.. my guess is that like disturbed said it is going to require a script and a registry value.  I thought that winrar might have something like that but it doesnt look like it.

Otherwise you could build php based login page with a db backend.. and limit the user to one login.. that is more work than what really needs to be done.

[solidsnake]

yea i agree swimmer , that is ur good idea, php based login, but see wont he be able to right click and save pic after login even once. try to figure something for that . and my prob solved

hey.... solidsnake

I will PM you my email address... send it to me and I will put it online for you and make it difficult to capture -- it's save resistant... not save proof, lol -- if someone can view something they can get it, but I will sure as hell make it difficult, after I have finished I will let you know how I did it

the only way it can be does is if you made a php script that would stop the save as fuction. but that is worthless because anyone can do printscreen. so it can't be done unless you could stop printscreen as well.

CA3LE thx a lot. i only needed to learn the way. but now i will contact you when i need to . thx again. and thx dlewis, for replying. by the way printscreen is not a prob. no one i know can easily do that or would wanna do that

Hi solidsnake;Do you realize how easy it is to do a screenshot?It's very basic & doesn't take much tech knowlege.I think even Windows as early as 95 can do it.You probably know how so I won't post instructions.

CA3LE is your best bet & even he said he can't make it copy proof.

On suggestion I can make is use as small(least pixels) of picture as can be viewed.This way if they copy & try to enlarge it the quality will be bad.

[netmasta]

I'm not sure what kind, but I do know that there some coding that prevent screenshots from being taken. I know survey sites for example use them. Of course you could probably find the pic url in the source code. A watermark is also another idea.

[resopalrabotnick]

my best guess would be the following.

write a program that is able to hack the picture up into random segments.

make a vid card/screen combo that gets at least 100 Hz a minimum requirement.

now, a tv only displayus 25 pictures a second (actually 50 half images)

to make screencapturing more difficult the program should only display a quarter of the picture in any one frame.

this quarter should be random segments of the pic. the program should then ensure that any one pixel gets refreshed avery 25th of a second, to achieve the tv effect. actually you can get away with as few as 18 or so fps iirc.

if a screenshot is taken it will contain only bitys of the picture. to get the whole picture several screenshots would have to be taken and blended.

the picture should be hardcoded into the program in an encrypted form so the pic can't be reversengineered out of decompiled code.

that's assecure as i can think to make it.

[cholla]

resopalrabotnick;that's definatly beyond my knowlege level but sounds good.

netmasta;Do you know a site that blocks screenshots.I would just like to give it a try to see the blocked results.

[netmasta]

I forget the name of the company right now, but I know they do it for a lot of survey type sites. E.g.: companies wanting feedback for soon to be released products.

[richcornucopia]

If they don't know how to do a printscreen, why don't you make it "save resistant" so they can't save it easily, but make it animated so it flashes up for like 2 seconds and then goes away.

[php]

As far as I know, the Printscreen key can't be captured with Javascript.  I think I tried it before, unsuccessfully.  And even if it could be blocked with Javascript, disabling Javascript would take care of that nicely.  But since this person(s) don't know how to take a screenshot....

[cholla]

Below is an example of a picture that wouldn't let me .Right click & save picture as.but print screen was no problem.

[php]

That website doesn't block right clicks for me.  I think I have Firefox disabling the 'disable right click' script though.

[cholla]

php ;I'm using IE & I keep the security pretty tight unless I need to lower it.So it might be something in that that is causing the block.I just ran across the site & got the warning .I thought it would make a good example for this topic.If i needed the pic I could have did the print screen wothout the warning .Then cut or cropped  it with one of my image programs.
