How do I prevent that downloaded pictures get 'stored' (?) in LibreOffice draw?

Every time I download a picture It gets stored in libre draw and I have individual go through to erase.

What do you mean by “stored in libre draw”?

@robleyd obviously assumes you complain about the effect that the image files get opened by ‘Draw’ if you call them from your file manager. If there actually is a bad file association by extension of the name, it should be expected nonetheless to be restricted to 1 or a few specific file extensions. How are these extensions?

Assumed you are on a recent Windows:
Do you know these extensions? Or are you a victim of the idiotic default setting for Windows to suppress extensions? Due to the even more idiotic ribbon-like interface the file manager comes now with, it is also difficult to tell you how to get a sensible setting. Try the rightmost tab of the interface (probably labeled ‘View’) and you may find (at the far right) an option like ‘Show extensions’. Always keep this option checked.

For the record: it’s called “File name extensions”.

Change, or remove, the file association for image types that are causing the problem; how you do this depends on your OS.
