for your site. some create images on the fly through php using gd

If there is no reason to create the images on the fly then a hard copy of
the image is always the best option. If you create images on the fly then
php will have to create the image everytime it is requested which wastes
server resources.

Yup and if you must create images in the fly for whatever reason atleast
cache the images that you have made

if(file_exists($img))
{
// include image
}
else
{
//create image
/ cache image
}

Every time you unlock a door, do you get a new key made? If the lock
doesn't change, of course you don't. But if the lock changed every
time, you would have to.

If the image is static, then just generate it once and save it. But if
the image is dynamic, then you need to generate it every time.

Most of the dynamic creation I've seen are things like CAPTCHA, graphs
dependent on changing data, etc.
