Are each of the pictures a single record in a related table that you are viewing through the portal?
If so you can use settings in the Portal Setup dialog under 'Format' to specify the starting row and number of rows the portal will display from the initial row, so you could have three instances of the same portal on the layout, setting the 'Number of rows:' on all of them to 5m and then change the 'Initial row:' setting to 1 for the first, 6 for the second and finally 11 for the third.
This will then give you all 15 related record flowing through the three portals.
Also switch off the vertical scroll bar for all but the last in so you only see any extra records in the last portal.
I hope this helps
That works perfectly. Thank you for your help.
No worries David, glad I could help.
