3 Images no alt attributes

I am using an SEO checker and it is claiming I have 3 images with missing alt attributes. Is this because of the theme itself loading the logo and other media? I searched my pages (not blogs) and all have alternate attributes.m What could be causing this flag? Also, Is this theme just .CSS hungry? I deactivated all the plugins and I still receive a report of 10+ CSS and JS files loading at initial sever request. I am at .41 page response but is this possible hungry theme is keeping us a little slow? Love the theme and have optimized it as best as I believe we can. Maybe I am missing something. Is there a particular file you recommend unloading from the theme at the initial load? Not complaining. Just curious about the 3 alt images, CSS, and JS files. Thanks for the beautiful theme! austinpedicab.org
