change size of photos on PRODUCT IN FO page

[matteoraggi]

I have enlarged the high and width of photos, to 350(weight) x 300(high) but all images look to be different, why?
What I must to to publish bigger images also first of zoom?
example:
http://www.estufe.com/index.php?main...roducts_id=595

Where did you change the image dimensions? Your javascript (which is the only way you allow us to see the image) says

<img src="images/grande.jpg" alt="07469" title=" 07469 " width="200" height="133" />

You need to change the settings in Configuration > Images >
Product Info - Image Width
and
Product Info - Image Height.

If you set them to 0, the actual pixel size of the image file will be used.
Your medium image file (at least for this product - 69k) is way too big - it should not be much more than 10k, maybe 20k for even this size of image.

You are using your large images for medium and small, and you can see the loss of quality when for instance Barbecue in Ghisa 07471 (490x312px, 32k) is reduced to 200x133px, still 32k. Make a smaller image in Photoshop or whatever and save it for web, and you will get better display and smaller, faster-loading files.

Also, your image filenames mean you will never be able to use additional images for a product without getting unwanted images showing up seemingly at random.
Read the FAQ on multiple images for a lot of good information.

I was needing to show IMAGE CENTERED and DESCRIPTION UNDER IMAGE, so my developer have changed script from this original:

<?php require(DIR_WS_MODULES . zen_get_module_directory(FILENAME_MAIN_PRODUCT_IMAGE)); ?>

<div id="productMainImage" class="centeredContent back">

<script language="javascript" type="text/javascript"><!--

document.write('<?php echo '<a href="javascriptopupWindow(\\\'' . zen_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $_GET['products_id']) . '\\\')">' . zen_image($products_image_medium, addslashes($products_name), MEDIUM_IMAGE_WIDTH, MEDIUM_IMAGE_HEIGHT) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>'; ?>');

//--></script>

<noscript>

<?php

echo '<a href="' . zen_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $_GET['products_id']) . '" target="_blank">' . zen_image($products_image_medium, $products_name, MEDIUM_IMAGE_WIDTH, MEDIUM_IMAGE_HEIGHT) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>';

?>

</noscript>

</div>

----------------------
to this:

<?php require(DIR_WS_MODULES . zen_get_module_directory(FILENAME_MAIN_PRODUCT_IMAGE)); ?>

<div id="productMainImage" class="" align="center" >

<script language="javascript" type="text/javascript"><!--

document.write('<?php echo '<a href="javascriptopupWindow(\\\'' . zen_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $_GET['products_id']) . '\\\')">' . zen_image($products_image_medium, addslashes($products_name), 200, 250) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>'; ?>');

//--></script>

<noscript>

<?php

// echo '<a href="' . zen_href_link(FILENAME_POPUP_IMAGE, 'pID=' . $_GET['products_id']) . '" target="_blank">' . zen_image($products_image_medium, $products_name, MEDIUM_IMAGE_WIDTH, MEDIUM_IMAGE_HEIGHT) . '<br /><span class="imgLink">' . TEXT_CLICK_TO_ENLARGE . '</span></a>';

?>

</noscript>

</div>

About images, often we directly copy tfrom producers, to do a more quick work, bcause we are publishing more of 2000 stoves, and working with lcients we'll do a better work step by step, now I go to read about multiple images, his is a nice idea!

i'm speaking about this file:
includes\templates\template_default\templates\tpl_modules_main_product_image.php

I hav try to replace the older, but again now I don't have control of size of this image..

[gjh42]

How do you not have control of the main image size? You can set that in admin > Configuration > Images > Product Info - Image Width and
Product Info - Image Height.

I was not knowin that I was free to do thsi so easily from admin yet, and I was giving to do this enalrgement of images to a developer, not expert in zen-cart, anche he have changed the code, but also when I put the old code, I can't change the image, so it is possible that control of image depend also from other files?
