lose images after chang system environment variables tmp & TEMP

I have libre office, without any problemas, for diferente reasons I had to change the values of the system w7 environment variables , tmp & TEMP, after that change happened that I lose the copy paste images into writer, calc, libre office in general.

I have reinstalled libre office obtaining the same behaviour of loosing my copy/paste images.
how can I resolve this problem?.
Is the reason of changing the values of this system environment variables the reason for this behaviour of loosing copy paste images into libre office.

What exactly do you mean by “losing copy paste images”? Images don’t show when pasting them into the document?
