1. Image compression

2. Using CDN

1. Slow speed
2. The large picture of HD has the possibility of dozens of m, the consumption of resources load slow.
3. To do a timer, is to wait for the IMG resources to load the page again, so do not see the process of the picture brush

Simple solution other answers have said, the landlord can refer to the next.
Say two ways to improve the user experience in a slightly more troublesome way:
1, picture block, so you can see the picture of a block of loading out, not to wait for a long time nothing, but also for large map multiple connections download speed can be slightly faster
2, JS asynchronous loading, create a Picture object loading pictures, etc. loaded and then displayed (many examples online)

P.S. Under Server check:
1. Disk I/O
2. Bandwidth
3, can consider vanish
4, static file server cache related to the head set to No, cache time and so on.

P.S.S. Can check the local to server download speed
