Javascript: getting the width of an img element

[harb]

Using Javascript I have been able to select an image element (an \[code\]HTMLImageElement\[/code\] object, say \[code\]img1\[/code\]) in my html document. I can also get its style using \[code\]img1.style\[/code\]. However, the following returns a blank alert:\[code\]alert(img1.style.width);\[/code\]whereas this used in the same position works fine:\[code\]alert(img1.width);\[/code\]so I don't think it's a problem with the image not having loaded yet.I can set the width using either of the two options, though, and I like using the first, of course. But why can't I get the width using the first?It's not so much the task I want to accomplish that's the issue here (I can do that in the second way); I want to learn what's wrong with the first way.
