[ZPT] trying to write an image folder page...

[Pete Phillips]

Hi

I am trying to write a zope page into which our staff can upload images
of wounds, and which will automatically create thumbnail images, and
display them in rows (using a table) so that I can get 4 thumbnail
images per row.

My problem is that it doesn't make sense to me why the first row will
only have 2 images, whilst the rest are OK at 4 images per row. For
example, I currently have 15 images in the folder, and they come out
like this:

1    2
3    4	  5	6
7    8	  9	10
11   12	  13	14
15


What I want is:

1    2	    3	4
5    6	    7	8
9    10	    11	12
13   14	    15  etc etc.


Code at the end - any thoughts appreciated:

Regards,
Pete
