Well my site allows users to generate images using PHP's GD library and then place the url/image on other sites for other people to see. These images change every now and then when a user levels them up or what not. I'm just wondering would generating the image code and then placing that in mysql and then echoing that; would that save more ram than having to generate it every time someone views the image?
I'm not really worried about slowness unless it's incredibly slow I just want to save more ram.
