v3.28 Images not working - Page 1

i've never used images in a pdf before so i started with a simple code:
<img src="demo.png">
but i get these errors:

why isn't it ginving a filename here: "File()"?

you have the safe_mode on, and png with alpha need to write temporary file that safe mode does not alow

try to use a png with no alpha,

nice, that works!
