Thanks OriginalEXE , placehold.it not works for me (Your IP address based on the country, region or network has been flagged by the website owner )
top 8 placeholders , only PlaceKitten and Placedog works for me
PlaceKitten is unbelievable fast (just like opening the local images)
Placedog is unbelievable slow
LoremPixum is quite unstable :

Additionally, a 503 Service Temporarily Unavailable error was encountered while trying to use an ErrorDocument to handle the request.others are just can’t be opened
Why don’t you save those images and host them on your own server?
