Group headings in multiple column report

[AChir]

I have a report which shows photos in four columns. The photos are grouped with a group header. I'd like each new group header on a new page (no problem) but would like it to go right across the page and to start on the left hand side of the page (no luck). At the moment, if the last photo is in column two of one page the new heading is in column three of the next page rather than on the left. Any help appreciated

Thanks

Can I modify my question? How about moving the heading so it is always in column 1? i.e. can I stop it from putting the heading in column three etc

Thanks for any ideas
