图像加载时间在html和php页面中需要更长的时间?

It been like 1 week already i am trying to solve this without success , The images inside my server loads fast when i open them directly ex: direct URL it takes around 130ms while showing the same image in html or php ex: inside page pages takes around 20X longer load time 2.52s.

I have noticed that this problem happens in inner pages only while index.php works fine.

I though at first its a codding error or something but then i have made a test page that only have this code on it <img class="logo-btn" src="images/logo.png" /> Test Page and the load time for the same image is 2.5s , while it takes only 130ms in the direct URL as i said.
