Mick,

to load up a jpeg you need the full address beginning with http:// etc

Try using jpg on the forums address instead. It may work? I thought it did once for me.

Otherwise open and resave the image(s) with a simple photo editor and resave as .jpg

Jpeg is apple based. It may work on newer versions of this software. But not yet.

Regarding the movie file. You need to load it to the internet, a hosting address of some sort. And include the full internet address beginning with http:// etc

Users may need to download it to view it, or can stream it depenind on their own device type and software.
