This is cross-browser capable
1. javascript:
Edit your chat.js.tpl.php, after the sequence on regex, about line 1590:
insert 2 lines:
- Code: Select all
rx = new RegExp('\[img\]\[](.+?)\[]\[/img\]','ig');
msg = msg.replace(rx, '<img src="$1">');
scroll to the top, and add:
- Code: Select all
function popUp2(URL) {
eval(window.open(URL, 'popUpWindow', 'toolbar=0,scrollbars=1,location=0,statusbar=0,menubar=0,resizable=1,width=440,height=400,left = 100,top = 60'));
}
2. css
In the chat.html.php, at the start, add:
- Code: Select all
a.imgRollover {
width:22px; height:22px;
margin:0 5px 0 0;
float:left;
background-image:url("themes/default/images/imagesm-off.gif");
}
a.imgRollover:hover {
background-image:url("themes/default/images/imagesm-on.gif");
}
In your chat.html.php, before the strong button, add:
- Code: Select all
<div class="pfc_btn">
<a class="imgRollover" href="javascript:popUp2('uploadimgchat.php')"></a>
</div>
Upload the three files and rehash.
3. ftp access
FTP access your server and create a folder called "shareimg" and CHMOD the folder to "777"
4. upload file
Then create this file, named 'uploadimgchat.php' and put it in the same folder as your main chat page:
- Code: Select all
<style type="text/css">
<!--
.style1 {
font-family: Verdana, Arial, Helvetica, sans-serif;
font-size: 12px;

.style2 {

}
.style3 {
font-family: Arial, Helvetica, sans-serif;
font-size: 14px;
font-weight:bold;
color:#303030;
}
body {
background-image: url(themes/default/images/background.gif);
}
-->
</style>
<script language="javascript">
function NoConfirm ()
{
win = top;
win.opener = top;
win.close ();
}
</script>

This can be any JPG, PNG or GIF image on your PC,<!--next comes the form, you must set the enctype to "multipart/frm-data" and use an input type "file" -->
<br>
provided it's no greater than 300Kb </p>
<span class="style1">
<form name="newad" method="post" enctype="multipart/form-data" action="">

<tr><td class="style1"><input name="Submit" type="submit" value="Upload image"></td></tr>
</table>
</form>
</span>
5. create images
you need an image button and a rollover button.
Eg:
Natural off state:
http://www.ninjaschat.com/themes/defaul ... sm-off.gif
Toggled on, by mouse rollover:
http://www.ninjaschat.com/themes/defaul ... esm-on.gif
This is the successfully uploaded image:
http://www.ninjaschat.com/themes/defaul ... /check.png
----------------
The image is set to display as 320 pixels if larger than that, otherwise, it's natural size
