Images size reduced even when picked from camera roll

this is however stated on the Data Collection User Guide>

If you want the original, full size image we recommend taking the photos outside of Epicollect5, then import them in Epicollect5 using the image picker when adding an entry. That way the original photo is saved in the device gallery app.

Is there any way to make this option work? My project would be all about crowdsourced images. Thanks!
