Positioning photos in a multi-column page

[didlinghill]

I need to compile an A4 newsletter which has two columns and I need to insert text-wrapped photographs in various places. However, whenever I do any editing, the illustrations have a mind of their own.
I realise I can control positioning and type of wrap, but what do I do if I just need an illustration to move and stay where I place it - manually. I do not wish it to move with the text or anything else, I just need to annul the location setting so that it is readily mobile. There does not appear to be any setting other than those with specific location, and I just want to cancel these restrictions - but this does not seem to be possible!
Any advice will be greatly appreciated.
