You have an extension, maybe a plugin, which is compressing your html, css, and script...

This may be the reason.
Try to view in its options, after having check by disabling it, to make sure it is the reason.

No, you html code is still compress! (right click, view code source)

We can't tell you what to do about others extensions that are not by JoomliC, we are not Superman!

You have install something that disturb multiple loading of the same image, so you have to check all your extensions one by one, and when find, ask for support on the appropriate website..

Don't forget that when you unpublish an extension, you need to empty cache of your joomla site!

Good Luck !
