Firefox… Help needed

Hello fellows. Need your help here.
If i’m on an image site and want to watch a thread with images it takes time to load the images. Altho i got a 25mbit internet connection.
Sometimes the images don’t even load and i have to rightclick on “image” a few times. Is this normal? I just re-installed firefox again :s
Answer #1
Is this image site 4chan by any chance?
Does it do it with another browser?
If it’s any image board like 4chan their image server gets attacked often so it could just be slow to respond.
Answer #2
No it’s just some regular fun belgian site. On 4chan everything goes well.
Answer #3
Could be a few things.
1) Is it just this site?
2) If so it could be the server load?
3) What is your ISP?
Answer #4
My isp is Telenet Operations Belgium. I also have the problem on Facebook that the images not loading, but that could be facebook as it’s loading slow last times
