These days more and more images decorate our web apps/sites; so sending them in one bundled rush would give us a significant performance boost :-) ! I have discovered support for CSS and script file bundling; but not for image bundling ... A product like Morfik does offer this ... Will Telerik offer that, too ?

Hello verlsnake,

Almost all RadControls for ASP.NET AJAX skins use CSS sprites, so that the number of images sent to the client is reduced to a minimum. There are controls/skins, which use only one image now and we are constantly improving the others.

Let us know if you need more information.

Okay, so for Telerik RadControls themselves image bundling does not provide any benefit; but what about chunks of HTML which are mixed with RadControls and CAN contain lots of images ? Because images cannot be replaced by CSS sprites in all circumstances.

Hi verlsnake,

The functionality you are talking about is a little out of scope for a UI component suite such as RadControls, but if you provide some more information about this "image bundling", we can take a closer look. Can you provide some more details about this feature, or send a link? I searched for any information available, but found nothing.

I know that image bundling is in the works at Morfik (http://www.morfik.com/); but have not found information about that on their website ... No idea how they accomplish some sort of image bundling ... Since You do already CSS and JS file file bundling, I thought it was not out of scope ... 
Please consider this thread as answered then ...

Hello verlsnake,

Yes, we combine CSS and JS files, however, these are text files and things are quite different - when the files are combined, their content remains intact and is usable by the browsers. I am not sure how images, which are NOT used as sprites (i.e. background images), can be combined and used by the browsers afterwards - the result should be a large image, which cannot be used in a standard scenario, e.g.

<img  src="...."  alt="..."   />

On the other hand, combining images to be used as background images (a.k.a. CSS sprites) is possible and we are already doing it, as I said earlier. By the way, I looked at some videos on the Morfik website and it seems to me that the image bundling, which is carried out in relation to some image effects, is namely creating CSS sprites :)

Thank you for this question though.
