Report with image / howto use nvl

Question

HI to all,
i'm playing aroun with image inside a report:
I would like to use an nvl function with an image: here the code, taken from an example app:
select
"PHOTO_CATALOG_ID",
"PHOTO_NAME",
"DESCRIPTION",
"UPLOADED_ON",
"MIME_TYPE",
'<img src="#OWNER#.display_thumb?p_photo_id=' || nvl(PHOTO_CATALOG_ID,0) || ' "/ WIDTH=100 HEIGHT=100>' thumbnail
from "PHOTO_CATALOG"
where
instr(upper("PHOTO_NAME"),upper(nvl(:P1_REPORT_SEARCH,"PHOTO_NAME"))) > 0 or
instr(upper("DESCRIPTION"),upper(nvl(:P1_REPORT_SEARCH,"DESCRIPTION"))) > 0 or
instr(upper("MIME_TYPE"),upper(nvl(:P1_REPORT_SEARCH,"MIME_TYPE"))) > 0
I would like to have a fixed grid of image 6 col * 2 row: that's quite easy however what doesn't work is nvl(PHOTO_CATALOG_ID,0): i got a missing image, but image with photo_catalog_id=0 isn't taken at all.
For image =0 i've uploaded a white image.
Anywhere if someone has another solution / idea for making a thumbnail like app in apex, wasn't bad to hear...
However: i don't want a report with an image col. I want different image (let's say that i would like to have the grid 6col * 2 row) with pagination style.
Each image should stay in a row of image table.
Thanks a lot
