This wont make you happy certainly. In this regard, if you wish to prevent this lag time for loading image in your navigation, an Image Preloader Script can be the solution. Let’s see how you can do it.

Add the following Javascript snippet just above your closing head tag:

<html>
<head>
<script type=”text/javascript”>
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf(“#”)!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
</script>
</head>

Then add the full url’s of the images you want to preload in the body tag.

In this way, you can easily reduce the time of loading your mouseover image.

JSN ImageShow is a flash image gallery that you can put it in your Joomla powered website. JSN ImageShow suports JPG, PNG and GIF image formats and you can put your image in any order you want. If you want to share images from Flick or Picassa, you can connect JSN ImageShow to your pictures. Also you can configure the width and height of your slideshow. You can specify the width and height in pixels and also in percentage.

If you want to put a background to your slideshow, you can choose one of your own or you can choose one from the numerous predefined images. You can also add captions: text font, color, alignment, background color, opacity, positions. After you finished setting up caption, choose from numerous effects, image motion, zooming and 3D image transition effects. If you are afraid that somebody will steal/borrow your photos, you can add watermarks. You can do this by putting an image as an overlay above slideshow images and configuring it’s position and opacity.

JSN ImageShow is available in 3 versions: Free, Pro and Developer. For the free versions there are a few restrictions: maximum showcase/showlist amount is only 3 and maximum images per showlist amount is also 3. If you want more you will have to buy the pro version which costs $39.

With Registration Validator you can block not only usernames or IP addresses but also you can block domains and subdomains.

Blocking an entire domain (including subdomains) is very easy. Just put before the domain a full stop (e.g. “.webdev3000.com”). Any entries without a leading full stop (period) are treated as specific (i.e. only that domain and none of its subdomains are blocked) .

To block an IP or IP ranges replace part of the IP with * to match any similar IP (e.g. 192.168.*.* will match 192.168.1.1, 192.168.3.4, and any others beginning 192.168).

Another feature of Registry Validator is the ability to check email addresses for valid DNS entry.

Registration Validator offers Botscout integration. Botscout prevents bots from registering on forums, polluting databases, spreading spam, and abusing forms on web sites. This is done tracking tracking the names, IPs, and email addresses that bots use and logging them for future comparison. Using Botscout the IP and email address will be checked and blocked if the IP and email are in Bouscout database.

With Registry Validator you can check email credibility against disposable hosts and fake accounts using http://undisposable.net/. This way you can prevent userbase contamination by fake accounts.

Compatibility: Joomla, Community Builder( version 1.2), AjaxRegistration and Virtuemart .
