Pic Security

[V@no]

Is there also a way to protect the thumbnails with the "hides location of the pictures and adds antileech" version?

sorry, not with this method.
This method allow save only one location per page.

I see. Any other way to protect the thumbnail path?

hi!

I use the "hides location of the pictures and adds antileech" codes from this thread and i'm very happy with it.
For registered users I would like to offer a possiblity to directly link to the images and give them the code to copy and paste like

Code: [Select]

<img src="....">
or maybe even with bb code etc.

How can this be done?

Greetings,

I just wanted to share with the public with another way to secure pictures, that I made long time ago and successfuly have been using on my site. It hides location of the pictures and adds antileech as well.

it hides the location well, but when you save the pic with right-click (my site) , the picture only can be saved as .bmp, and no name of the picture is shown.

That is only in IE browsers, because it seems only IE obbeys site's requests not to cache images. Remove all "no-cache" headers from the code.

I removed all "no-cache" headers from the code, but there seems to be no diffrence. The picture can not be saved as jpg, but only as bmp, and  picture name is not showing up when saving with right click.
ex : http://www.edupics.com/coloringpictures54.htm

only "no-cache" headers i found :

admin/checkimages
header("Expires: Mon, 26 Jul 1997 05:00:00 GMT");             // turn off caching

admin/adminfunctions
header ("Cache-Control: no-store, no-cache, must-revalidate");
header ("Cache-Control: pre-check=0, post-check=0, max-age=0", false);
header ("Pragma: no-cache");
header ("Expires: " . gmdate("D, d M Y H:i:s", time()) . " GMT"); 

--couldn't find any more "no-cache" headers--

... The picture can not be saved as jpg, but only as bmp ...

it is a problem with not only your MS-IE ... your Temporary-Internet-Files-Folder is too full .... 
go to : MS-IE -> Options -> Generally -> Temporary Internet Files -> Files delete
(or similarly ... I use a German Version ...  )

now the problem should be repaired ...

also to find here : http://support.microsoft.com/default.aspx?scid=kb;de;810978

[kief24]

no, i already tried that...
even if temporary-internet-files-folder is empty, picture only can be saved as .bmp

you can try it on
http://www.edupics.com/coloringpictures54.htm
i suppose you'll have the same problem.

if i try to save with firefox :
it saves the pictures as .gif with the name "show.php"

( the pics are jpg's )


i have the mod " Cache System for 4images v1.7 " installed on the site, but i supose this is not the problem, because if i disable the caching, problems stay the same

... you are right ...

Your server still sending

Expires: Thu, 19 Nov 1981 08:52:00 GMT
Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache

- that's why.

It could be the server's setup itself...dont know.

[kief24]

i checked and on server side no caching is disabled.

i searched trough my entire site, nothing can be found that disables caching...
searched on the words cache, pragma, header, no-cache, ......nothing.

I had the same problem ones, and turned out I had to change something in the php.ini or in apache config.conf I cant remmember exactly now...
For now, can I see your phpinfo?

[edit]
I think it was in php.ini I had to comment out this line:

Code: [Select]

session.cache_limiter = nocache[edit2]
if that is the reason, try add on top of global.php:

Code: [Select]

session_cache_limiter('none');

[kief24]

the adding of the code on top of global.php didn't work

i removed the modifications.
if you print trough right click or copy and paste to Word, the error message was shown....


just curious,

you wrote in the lightbox-for-guests mod :

and this are the headers from my site:
Quote

that's the same code as sent by my server, preventing the caching :

Cache-Control: no-store, no-cache, must-revalidate, post-check=0, pre-check=0
Pragma: no-cache

do you know where that/your code was generated ?

But again, I'd like to see your phpinfo

My domain is on shared server so i do not have access to the php.ini file
