This mod was intended to address two issues.
1. Watermarking product images so nobody (else) can use them.
2. Creating small thumbnails to increase page load times.
The conventional solution to both these is to generate a second set of
images, based on your normal product pictures, and refer to these instead.
With over 1000 product images to deal with, and the almost certain
confusion between trying to keep THREE sets of images in step, I decided
this was not a good idea. We frequently re-take pictures, and I did not
want the hastle of resizing and staming over and over again.
Why not just let the webserver do all the work?
This mod addresses this. You don't have to change any image. You don't
need to create any more images. It's a very simple mod to one file of
oscommerce, and you can even refer to your pictures remotely (e.g. use
them on eBay) and it STILL works!

but a big problemafter use the watermark parts
all jpg have the watermark, even the background , so button, box, banner...........
and the other problem is some images will not display
A very simple extension to the flom's package.
This package only contains the thumb.php file which has been patched. PNG, JPG and JPEG are now supported (instead of just JPG files).
Hope this can help.
package has everything u need.
with this package it is possible to create 3 different sizes of thumbnails. also works with "more pics"-contribution. description in german.
on my page i realized the following: 130px thumbs when searching etc. 350px thumbs in product info site. then 750px thumbs in a pop up window from product info site....
first install as usual, then see WICHTIGES.txt
have fun
Hi all : -),
if anyone want to center watermark on the image i made a small upadate. Instalation is simple, overwrite image.php on your server only.
I changed 1 part of thumb.php so it improves the quality of the thumb. It's still not the best looking, but it's still better.

Most people are using this contrib without any problems, and are more than satisfied.
A few, however, have some question on the beginning of their way, so a support thread was started to concentrate all questions and answers in one place.
