HOW-TO: Image Preparation

[xinde]

I have the thumbnail images in the thumbnails folder. However, The site is not using the real images instead of using the large image to scale to the small size. I don't know how it can be turn the auto scale and use the real image.

Your help is appreciated.

Thanks for this tutorial.
I have Zen Cart 1.3.9h.
I have set up images/rings and images/large/rings. No MED as the lage photos are only 200 x 200
I have images/rings 95017016.jpg and images/large/rings/95017016_LRG.jpg
The pop up shows only the small image 95017016.jpg
I moved the 95017016.jpg to images/95017016.jpg _LRG to images/large/95017016_LRG.jpg
Same problem
I also tried images/rings 95017016.jpg and images/rings/large/95017016_LRG.jpg. No joy, still only the small image.
From what I can see images/rings 95017016.jpg and images/large/rings/95017016_LRG.jpg should be the one that works.

Take out the + for the domain url. I can not post the name it turns to ###, the first word is german for jewelry (##############).

I am one step further.
I changed the image called 95017016_LRG.jpg so I could see if the correct image was loading. The correct image loads (95017016_LRG.jpg ), but at a smaller size than 95017016.jpg so my problem must be in jscript_main.php.
I have :
?>
<script language="javascript" type="text/javascript"><!--
function popupWindow(url) {
window.open(url,'popupWindow','toolbar=no,location=no,directories=no,status=no,m enubar=no,scrollbars=no,resizable=yes,copyhistory=no,width=200,height=200,screen X=250,screenY=250,top=250,left=250')
}
function popupWindowPrice(url) {
window.open(url,'popupWindow','toolbar=no,location=no,directories=no,status=no,m enubar=no,scrollbars=yes,resizable=yes,copyhistory=no,width=600,height=400,scree nX=250,screenY=250,top=250,left=250')
}
//--></script>

This is saved under modules/mytemplate name/pages/product_info/jscript_main.php
I also tried:
Change original file name to jscript_main_org.php and then save the new /jscript_main.php
in place of the original.
This all has no effect??

I have a tip for improving the image quality of th smaller images.

The method to start with the large images and reduce down to medium and to standard is indeed the right one. BUT it leaves you with rather motty thumb nails.

You can enhance that by letting your image processing software brighten the image a little and then do a mild unsharp masking on the thumbnails. You will notice that the image is a lot brighter after that. Unsharp masking brightens the highlights and makes the edges more clear.

The size of the file is important too. When you use unsharp masking, you can put the quality slide of the JPG export higher - more compression, faster processing.

I'm not familiar with Photoshop, only with Corel Photopaint. Photopaint allows to record a sequence of steps and then save that to a file. That file can then be re-used on a batch.

Step 1:
- |image|resample (use percentage) to 33%
- |adjust|brightness-contrast - intensity: 0-7-5 (just a little, you can experiment with this to set it to your liking
- |effects|sharpen|unsharp masking - 120 -1 (or 2) - 1

Save the recording. (.csc file)

Start batch processing, load the files you want to do, select the just saved csc-file, select what to do with the processed image, press start en lean back...

Another tip. For renaming ALL your files in a specific folder all at once.

Open the windows Command prompt.
select the disk where the images are located.
In my case its the D: drive, so at the prompt I type: D:\ [enter]
then I go to the disk where the images are:
cd \images[enter]
cd \medium[enter]

here is where my medium sized images are located.
then comes the magic:

type at the prompt:
rename *.jpg *_MED.jpg[enter]
Don't get nervous.... it takes a while before the prompt returns, but it works well.

To go to the large images file you can then type:
cd ..\large

or

cd..
cd \large

and then repeat the whole magic

Hi i have read through your great image preparation post. thankyou for that but i cannot find how to fix one problem that i am having.
All my pictures display correctly except for the manufacturer images on the product page they are displayed very large and go off the screen in some cases.
Is there anyway how to get them to adjust to the same size to fit in the sidebox?

a link to one of the products is http://www.acecomputers.com.au/index...products_id=16

any help would be really appreciated as i dont have any coding knowledge.

thanks

Quick answer - you don't (not without a lot of work). ZC is not geared up to use product pictures from an external source - and you'll be really crippling yourself with regard to SEO with all the external links and the page load speed penalties.

We have our images in images/product_images. How do I handle additional images and _LRG and _MED. I tried images/product_images/large and images/product_images/medium but the system does not find the other sizes and always defaults to the small image.

Thank you

Dooohhh... I got it - images/large/products images/medium/products
