Odd file opening problem

[ppppenguin]

All image formats are explicitly linked to Irfanview. The problem seems to be that the default on double clicking an image on my phone is "preview" which goes to the Microsft viewer. Right click and select "open" and it opens in Irfanview. On image files elsewhere the default for double click is "open". I've just looked on the right click menu and there is a preview option. Which opens the file in the microsft viewer.
