should replace loop with dst = append(dst, src...)

26func imageCopyB(src []image.Image) (dst []image.Image) {
27 dst = make([]image.Image, 0, len(src))
28 for _, img := range src {29 dst = append(dst, img)
30 }
31 return dst
Description
There is no need to range over the slice and append elements one by one;
instead, use append because it's clear, simple, and idiomatic.
Bad practice
a := []int{1, 2}
b := []int{3, 4}
for _, v := range a {
b = append(b, v)
}
Recommended
a := []int{1, 2}
b := []int{3, 4}
b = append(b, a...)
