When including pictures into the home page it might happen that the pictures are displayed locally on the hard disk but not on the server.
Reasons could be:
- Linking of the pictures is not correct (e.g. using the absolute instead of the relative path).
- Case sensitivity of the linked file has not been followed.
- Case sensitivity of the linked file's directory has not been followed.
- The file hasn't been uploaded to the server yet.
For troubleshooting please check the aforementioned points. Especially case sensitivity causes troubles. Unix systems like most web servers distinguish between capital and small characters.
