If Image Icons are used space gaps between Icons are undefined and different

Hi All,,

just come back again on a design Issue I mentioned some weeks earlier.

If e.g. a PNG (Image Icon) is used insteed of a standard font awesome Icon fromlist an undefined and bigger space gaps is seen between the Icons. Space gaps then are different to each other. Please see sample on WP https://www.friesenlandhaus-norddeich.de, there is a bigger gap between the Icons from Instagram (png Image Icon) and Pinterest (font awesome Icon).

Would be great if this Issue could be assessed, evaluated and solved.

Thx for your support and help. BR
