Replacing home button with image, is it bad ?

hello, hope you all having a nice day,
first of all you guys are amazing, very well done with the amazing work.
i really have some basic questions hope you can help me around here, as we are already on half way to replace and almost completely set up whole theme on our needs. can you please guide me can we replace home button or any category titles with images and if we successfully do it, is it really bad for search engines or crawlers ? some of our mods are suggesting to let them be but some insists to change em,
please suggest us and guide us how we can.

The site you’re referring is not under Shapely theme or any colorlib theme, can you confirm that is the right site?

Let us know,
