Emailaddresses as GD image

Hello all,

At my forum, onzinforum.nl (Dutch),
we would like to have all the emailaddresses shown as GD Images instead of plain text, to get rid of spam :)

is there someone who can help me ?

Hmm ... why not just disabling display of email-adresses at all?

corn	06-14-2005 06:48 PM

We do not want to disable it, because the forummembers would like to see eachothers addresses, so they can email with eachother :)

Andreas

They can email each other without having to display their eMail-Adresses :)

corn	06-14-2005 07:05 PM

Yup, I know, but we do want to have the addresses visible, but as an image :)

Makes no sense. Or Manybe it makes sense but it's ....

Oh well...i guess what you want is something like the gmail images. There could be a way to make it that when it sees an email address it does a "replacement" of sorts and creates the image instead....

I will thell you this: it would be VERY CPU intensive on the server...picture this:

1 thread: 50 Posts: each with a email address.....

THEN...Multiply that by the number of threads in yur forum ....then pray your Hosting company doesn't shut down your site.

This is not true, because email addresses are not shown in the postbit, but in the public profile.

Even if you only display them in the profile, this would be a real CPU Hog ... and IMHO it's absolutely not worth it.
Use teh secure mail feature, if users want to directly mail each other they can exchange their adresses via eMail or PM.

corn	06-14-2005 07:36 PM

omg :D

I really apreciate your info, but thats not the info I'm looking for.
I know it will be a CPU killer, but thats my problem :)

btw, NOFI

jugo	06-14-2005 07:39 PM

LOL....

What's NOFI?

corn	06-14-2005 07:41 PM

No flame Intended

But,
if possible, please advise, because the spam is killing me :D:D:D

jugo	06-14-2005 07:49 PM

Get this: http://playtime.uni.cc/downloads.php?page=gmail

I'm sure you can hack it into a function and make it parse the email addresses...I did it a while back for something else (can't find my modified code though sorry) but that was my starting point.

Good luck...>And if your host boots you, get in touch with me...LOL.

BTW, NOFT

corn	06-14-2005 07:56 PM

Thanks a lot !

I will release my hack soon :D:D

And btw, my current hostingprovider sucks :D so we don't care :D:D

jugo	06-14-2005 07:59 PM

Well then look at my signature.... ;-)

corn	06-14-2005 09:16 PM

its working !! :D:D

howto:

create a email.png file (ms paint, photoshop) size 275x20.

create a file called email.php, wich contains te following:

Code:

<?php

    header("Content-type: image/png");

    $im     = imagecreatefrompng("email.png");

    $color = imagecolorallocate($im, 0, 0, 0);

    $px     = (imagesx($im) - 7.5 * strlen($user)) / 2;

    imagestring($im, 4, $px, 1, $user, $color);

    imagepng($im);

    imagedestroy($im);

?>

upload these to files to the forum root dir.

open the MEMBERINFO template, and search for $userinfo[msn]
and replace that with <img src="email.php?user=$userinfo[msn]" border="0">

thats it !

good job corn!

you should probably close this thread and start a new one with your code as a new Hack. that way, i can click install.

Andreas

06-14-2005 09:30 PM

Erm ... that does not make sense.

1. $userinfo[msn] is not the users eMail-Address - it's his MSN ID (which can be his eMail-Address, but can also be empty)
2. You still have the eMail-Address in the HTML - and thus spammers can still process it automatically.

If only his method of doing it worked. Right now he has high server load without accomplishing anything.
