Hi all,
Any ideas how to retrieve image size without loading it?
What i found so far is no good: using the img tag or the Image object won't work, since the image has to load first (which happens asynchronously). On the other hand, using the onload function is also no good: i lose context till the loading is finished.:(

Any Ideas

Hi tal

What is your server side technology ?

I think you can load your image on server side using an image manipulation library, obtain it's size and retrieve it on client side using AJAX.

Hmm, that's an interesting idea, i'm sure i can implement it easily.
Although it could have been much cooler to have something ready :(

To get the size of an image with javascript the image will have to be loaded in your browser first you could make a pre-loader (which i do not recommend) but the best way is just to get the image size with PHP,ASP,JSP or what ever serverside scripting you use.
