How Can I Show the Original Aspect Ratio?

If you have images that need to be displayed in their original aspect ratios, you can add the following to the plugin’s Custom CSS section (Instagram Feed > Customize > Misc):

#sb_instagram .sbi_photo {
    height: auto !important;
    background: none !important;
}
#sb_instagram .sbi_photo img {
    display: block !important;
}
