@waifu @nyanide ok so now with this you should get a thumbnail on the main page and then on click it opens the full image

#!/bin/bash
thumbs_dir="thumbs"
mkdir -p "$thumbs_dir"
img_tags=""
for image in assets/images/*; do
if [ -f "$image" ]; then
basename=$(basename "$image")
thumbnail_file="${thumbs_dir}/${basename}"
magick "$image" -resize 150x150^ "$thumbnail_file"
img_tags+="<a href=\"$image\" target=\"_blank\"><img src=\"$thumbnail_file\" alt=\"$basename\"></a>"
fi
done
cat template.html | sed "s#{{{GALLERY}}}#$img_tags#" > index.html
