You are using forEach() and DataSnapshot of /orders node where each child node seems to be a category and not the image itself. You'll have to loop over each image of the categories to list them:
firebase.database().ref("images").once("value").then((imagesCategories) => {
if (imagesCategories.exists()) {
var imageshtml = "";
// For each category
imagesCategories.forEach(function(categoryImages) {
// For each category image
categoryImages.forEach(function(image) {
// Append data to imageshtml from here
console.log(image.val().url)
console.log(image.val().title)
})
})
}
});
