Product images not display after move site to new server magento
I also had this issue in past, When i move my magento site local to new server suddenly images disappear on front end and back end too.
After very debugging i got the below solution.
In my case i went to /public_html/media/catalog/product and renamed all the capital letters to lower case.
If your all directory has lower case then renamed it to capital letters.
After this my all products displays as it is.
I hope it will help you.
