Also, for inline images without explicitly defined
tooltips, the
image name is used as the tooltip even though it
is also shown in the URL
when mousing over the image. Neither of these automatic tooltips are really
useful, and they slow down page load time on image-heavy pages.
They might not be useful for you, but they are useful for others. On
what basis do you say they slow down page load time? I would be
surprised to find that supplying or not supplying alt text made any
difference.
You're right, this sounds like absolute nonsense. The time it takes to
set and/or display these tooltips is nothing compared to the time it
takes to download and display the images themselves. Image-heavy pages
load slowly because they contain a lot of images (surprise!), most
other factors are negligible.
