 Click Here to Download JQueryImageOverlay.zip

Image overlay means give text caption to image. Using Image overlay we can provide more details regarding image on mouse hover of image. This overlay is common in modern websites. We are using JQuery Image Overlay Plugin. This is a javascript file which you found online as well as we place this javascript in our example so you can download that from our given asp.net example.

There are many options and advance settings provided by Overlay Plugin javascript "jquery.ImageOverlay.js". You can set without any options for simple purpose. There are options like border color, overlay origin, overlay color, and overlay text color, overlay speed, overlay speed out etc.

By setting this option you made you custom overlay, like border cover , text color , different In and Out overlay animation etc..
You can also use JQuery MetaData Plugin "jquery.metadata.js" to display meta data information in overlay.

Here is example for this.
In this example we take several images to display various uses of Image overlay with Asp.Net.
