Scale images

[adragan]

Is there a way to automatically scale a JPEG or a PNG to fit on the user screen ?

I have a lot of spare parts images scanned in 1000 resolutions and dimmensions

and I would like to put them on the screen of the user.

I can't scale them on the server because only god knows what is their local screen resolution and

most of the pictures go out of the available screen space.

I tried  Image.Autosize:=True but does not work.

Autosize:=True is not work, but You can use xtype:'image' , shrinkWrap:true

or use html frame with using the HTML <img> tag without specifying width or height works fine
