Get width of specific image

[Chris Falkenstein]

Hi all,  I created a Hanna Code that allows a client to embed a image.  First they upload an image to the page (using the images field).  Then they use Hanna Code to embed it.  The Hanna Code looks like the following.

[[image file='myimage.jpg' caption="my image" align='center']]

I'd like to set a max-width on the generated HTML img tag.  I need the width of the image.  How can I get it?  So I need a way to get the image width based on the name of the image? Any ideas?

Under the "Input" tab for the field (in question), you can set the max width and/or max height for uploaded images. 

However, if you are trying to output a max-width property for use with your hanna code, My "solution" might not be what you are looking for.

Thanks for the response. 

I need the width so I can set the max-width css property of the img tag.  I need the value of the width.  Is there a Processwire method/function for that which I can use when coding my Hanna Code?

$image = $page->images->get("name=myimage.jpg");
$image->width();
