html - Is there a way to prevent browsers from upscaling images? -

-

on webpage, use images 720px 480px. if @ them in firefox or ie (latest version) scaled up, considerably larger on screen original version in lightroom. if @ dimensions of picture on web though, says 720x480. if want files big should be, have set width-property 600px, think odd.. webpage uses bootstrap 3.3.4.

there may styles being applied bootstrap or else, causing issue. if in inspector of browser, show of rules apply given element. also, browser may zoomed. shortcut reset default ctrl-0, though there option listed in menus.
