Pagination and pl/sql

Question

Greetings,
I have the following piece of code that I'm using to display images uploaded through HTMLDB into Intermedia. My question is how to create pagination in the following sql statement:
select s.id,s.thumb,s.thumbname,s.image.getWidth()as width,s.image.getHeight() as height from islidetable s order by id
so that I can have it display x-y of z records. Is there a way in sql to select a group of records say 10-15 of 30 records?
Thanks in Advance,
Cliff
declare
obj ORDSYS.ORDImage;
ctx raw(4000):=null;
nxtseq number;
thisrowid urowid;
i_index number := 0;
i_rows number := 4;
inum number;
BEGIN
htp.tableOpen(cattributes=>'border=0 align=center bgcolor=black cellspacing=1 cellpadding=25');
select count(*) into inum from islidetable;
for b_rec in (select s.id,s.thumb,s.thumbname,s.image.getWidth()as width,s.image.getHeight() as height from islidetable s order by id) loop
if (i_index mod i_rows) = 0 then
if (i_index = 0) then
htp.tableRowOpen(cattributes=>'bgcolor=white');
htp.p('<td align=center><img src=xxutpa_mig.extract_thumb?p_file='||b_rec.id||'><br>'||b_rec.thumbname);
htp.p('<br>W:'||b_rec.width||' H:'||b_rec.height||'</td>');
i_index := i_index + 1;
else
htp.tableRowClose;
htp.tableRowOpen(cattributes=>'bgcolor=white');
htp.p('<td align=center><img src=xxutpa_mig.extract_thumb?p_file='||b_rec.id||'><br>'||b_rec.thumbname);
htp.p('<br>Width:'||b_rec.width||' Height:'||b_rec.height||'</td>');
i_index := i_index + 1;

Hey Vikas,
Yeah, these semantics have bitten me before. I'm doing a query and returning 14 records. Rather than display them in a 1x14 table, I want to split them up into a 3x5 table, displaying the first 3 records returned from the query in the first row, next 3 in the next row, and so on and so forth. Being verbose, if the query returned
Jane Doe1   131 W. University   Anywhere, USA
Jane Doe2   132 W. University   Someplace, USA
Jane Doe3   133 W. University   Elsewhere, USA
Jane Doe4   134 W. University   Nowhere, USA
Jane Doe5   135 W. University   Here, USA
Jane Doe6   136 W. University   There, USA
I'd like to be able to display it as such:
Jane Doe1                Jane Doe2               Jane Doe3
131 Univ                 132 Univ                133 Univ
Anywhere                 Someplace               Elsewhere
Jane Doe4                Jane Doe5               Jane Doe6
131 Univ                 132 Univ                133 Univ
Nowhere                  Here                    There
..and so on and so forth through the next 9 records. Given that my query could return hundreds or thousands, I want to be able to paginate every 15 (or however many I deem sufficient) records.
I hope this made more sense, and thanks for responding.
TIA,
