I notice that the html in WordPress for displaying an image is often something like this:
<img class="size-thumbnail wp-image-59" title="reflection one" src="http://xxxxxxx.wordpress.com/files/2008/10/snv31267.jpg?w=128" border="0" alt="reflection one" width="128" height="96" />
Does this mean that the full size jpg file (in this case snv31267.jpg (JPEG Image, 2816x2112 pixels)) is sent down from WordPress to the user and the user's browser resizes it to 128 by 96?
Or does WordPress do it cleverly and store various different sizes of file and send the appropriate one?
If the former, I will make an effort to reduce images to the maximum size that I make them viewable at.
The blog I need help with is noticeboards.wordpress.com.
