Hi Preeti,

As I see the images are served by your own custom handler. You should check if the names provided to it are correct and what it returns. You can try it outside of a rotator to test it, there should be no difference. In either case an URL is generated that is set to the src attribute of an img tag. If this URL is wrong or the handler does not return the expected data, then the issue is not with our controls. The demo itself does not use a handler, but builds an URL to a folder that contains the images in the site.

On the RadBinaryImage control - if you do not see it, the most likely reason is that your RadControls version is very old (around Q1 2009 or older), before the release of the control. To get it you would need to upgrade.

Thanx Marin..
   As you said I checked my code by applying debuger on my imagehandler but on runnig project the control is not going on imagehandler...I think there must be some other way to give the path of imagehandler. Can you help me in getting my images which are saved in sql database, to present them in a slide show I don't have a static folder of those images they are inserting by the end user so i have to fetch them from database only...there is no compulsion to use onlu telerik control.....I can use other controls also ...I refer many link but none of them are of use as they all were based on representation of static images...

Hi,

If the handler is not hit then the URLs that are constructed are wrong and you need to inspect and fix them.

We offer the RadBinaryImage control that can show binary data from a datasource as an image and, as we already discussed, you may need to upgrade your RadControls version to get it.

On other options - I am afraid I am not in a position to advise on other third-party software.
