thumbnail images

[esthera]

I need a way to create thumbnail images without a component that needs to be installed on the server.
I want it to make the thumbnail proportionate to the size of the image.
is there anyway to do this with just the img tag. (but proportionate?)

You may want to look into this:

A free .dll file that just needs to be placed into a folder with full permissions.

you can do it with just the img tag if you only specify 1 of the height or width. It doesnt physically resize the images in that it wont create a separate thumbnail image but it will display the original image at a smaller size.
eg if you have an image 100x200 and you say
<img src = "image.gif" width = "50" /> then it will display as a 50x100 image

I was watching this thread hoping someone knew a way to do this. I am going to be building a new site and this is one of things that I am going to having to do. A lot of the images files I have are not going to be the right size for the display area I am going to have for them. But I still want to be able to show them at their full size when someone clicks on them. I was going to try one of two thing. The first one is to try to use a width and height with a % instead of px. I haven't try it yet but cann't you do
<img src= "image.jpg" width="50%" height="50%" />
The other is to just resize the pictures through a program and save both picture sizes. Has anyone tryed to resize a image using % instead of px?

Edit: No it doesn't work just tested it. You can't use the height="50%" the width seen to work ok but that isn't a resize for a thumbnail. It looks like I will just have to have two pictures one thumbnail and one normal size.
