Displaying images dynamically from database:)

Hey guys do you have any samples that can display images dynamically from database(sql query browser) and display it on jsp and servlets?
The attribute for my image is called: image(varchar)
Thanks:)

Thanks:D

Ummm...varchar????

What kind of database allows images to be stored in a VARCHAR field???

You sure you aren't just storing the PATH to the image in that field, with the image actually in a disk file referenced by that path??

If you really have an image stored *IN* the database, it should almost surely be stored in a BLOB or BIT VARYING or similar field type. But, again, it depends on which DB your are using.

Ops sorry I made a mistake. Yeap it is the path for the image insetad of the original image itself. In eclipse web content I create a folder named images and it the folder there is Beanie image category whereby the image.jpg is encode in it.

Below is the code that I used to display out the images.

Code:

 
<td>
<div style=""><img border="1"
src="images/Beanie/<%=rs.getString("Image") %>" height="160" width="160" /></div>
</td>

Do you guys know how to display all the 100 images from the database dynamically?
Thanks:D

The software that I am using is called eclipse, tomcat6 and sql query browser.:D

I've never heard of "sql query browser" as the name of a database. But I think that's unimportant.

All you need to do is use the right SQL query and the loop through all the records.

Show the code you have in that page with the rs.getString( ). Where is the SQL it is using? Where is rs created? etc., etc.
