Changing an image block to another image on hover or rollover? in Coding and Customization Posted June 30, 2015 Hi Bernard! You're awesome. I'm trying to do what you describe above: have my grid gallery images change to new images on hover with CSS. Could you please share this easier method you mentioned? It's for www.killinit.in/copywriting. Going to have the images change from b&w to color images of the exact same size. I'm also new to this, so am a bit confused about how to store the images. Should I put them up somewhere like dropbox, or is it better to host them on my site with an unlisted gallery? Thanks so much!
