Help with simple PHP script and wordpress

gfdd · Oct 13, 2012

Hello,

I'm using a simple php plugin for my wordpress site.
THe plugin, just adds a clickable image on mouse hovering text links.
For any reason, i can't increase the size of the images shown, which by default is 80px
Here is the code. How to increase value, for example, to 550x220 ?

Thanks

	// If you want, and I would recommend it, add the style definitions for .avatarpop directly

Is that what

$wp_ozh_avatar['size'] = 80;
    // Size of the gravatar displayed (in pixels)

Does? Note that it probably doesn't make much sense to ask gravatar for dimensions that aren't actually square. In fact, just now I saw on the gravatar web site:

gravatar wrote:
You may request a specific image size, which will be dynamically delivered from Gravatar by using the s= or size= parameter and passing a single pixel dimension (since the images are square)
