- If i add a picture no text appears.
There is a warning about this in the box where you enter the picture filename: Alternatively, upload a file (formats supported: jpg, png, gif, pdf, ogg, mp3, mpeg, avi, wmv, torrent, asf) The word alternatively indicates that it’s an alternative to entering text.
- I do not understand this (in simple mode) Why is it EITHER /OR
The reason why is, i think, due to simplicity. Loading text or an image as a single item for the whole information storage structure (database) is simple than loading a complex item including both text and photo/audio/video. So first you publish e.g. text and then you add a photo as a comment. Or vice versa. Without any restrictions for further adding text or photos/audio/video.
- Why does the addition of a picture require you to choose from a limited # of focuses?
It is not required. “Add another focus” is an optional action.
