When image upload isn't required then this means that there are no 100% guarantee that image will be there.
For such cases in template, where image will be displayed we:
either display default image, e.g. <inp2:unit-prefix_Field name="ImageField" format="resize:100x100;default:img/no_image.gif"/>
- or place <inp2:m_if check="unit-prefix_Field" name="ImageField" db="db"> ... </inp2:m_if> around image display code
If none of mentioned above happens then horrible fatal error happens, that results in "The connection was reset
" message being returned from a web server with no idea about what caused it.
Ready for testing.
