Image Handler 2 (for ZC v1.3.8 ONLY) Support

Just to give you some more info, the preview image admin/images/ih-test.png does exist so I do not fully understand why the 3 png files do not show in the IH Admin-> Preview Tab.

I have done a server info - here are the GD bits that you may help you to help me!

OK - slowly but surely I am getting there. I believe the answer is here somewhere but to get the hover image larger I had to change the settings

In admin

Configuartion -> Images

Product Info -> Image Width
Product Info -> Image Height

Can someone tell me please what Zen Cart uses

Product Info - Image Medium Suffix and
Product Info - Image Large Suffix

for please as these are not Image Handler options.

Also, does anyone know why the PNG images do not display in the IH Preview page?

Darn it there is more - I asked before but my images aren't being resized in the IH/Product page where it displays 3 versions of each product image, namely Default Size, Medium Size and Large Size. The dimensions and sizes seem to be getting calculated and displayed correctly but all three images (for one specific image) are all the exact same image on the server.

Sorry for repeat posts - but I will get this to work and publish my findings!!!

Hi all,

me again. I don't like to flood the forum, but equally when I have an update I like to post it in case any of you are actively looking into potential problems.

I am beginning to wonder if there is a bug in the script.

Let me explain what I have.

I have a product with 3 images, called p.jpg, p_b.jpg and p_c.jpg.

When I look at the images in IH/product info I get this table

Image Default size Medium size Large size

p.jpg small p.jpg small p_a.jpg small p_.jpg
48X80 137X240 334X550
2kB 8.32kB 31.16kB

p_b.jpg small p_b.jpg small p_b.jpg small p_b.jpg
47X80 141X240 325X550
2kB 8.45kB 32.1kB

p_c.jpg small p_b.jpg small p_b.jpg small p_b.jpg
45X80 137X240 315X550
2.01kB 8.22kB 30.82kB

The image sizes seem sensible, but why are they all small?

Should I not see medium images in the medium column and large images in the large column?

Also, why in the row for p.jpg does it display p_b.jpg and p_c.jpg?

I am going to carry on my investigation and assume this is a bug and write a patch.

Is this a bug? Does anyone else have the same problem? I have a downloaded an old version of the file even? The file in question is admin/image_handler.php and the version info is

• @version $Id: image_handler.php,v 1.5 2006/05/01 12:16:43 tim Exp $

Sorry for clogging the thread!

Am going to make this my lsat post for now in case I start looking silly. I don't think I understand Image Handler as well as I should.

Ignore my table above. I was playing with _MED.jpg and _LRG.jpg suffixes. What are these anyway? When you ahve them IH shows a delete button? Can anyone send me some links explaining this?

With regards to IH/product info always showing small images - well I have fixed this in the code if anyone wants it? But is it really a bug or was it by design? Every image was going through this call with the 50 and 40 hard coded (albeit through a define)

get_resized_image(50, 40, [generic]).

THis was producing images 24X20??????

If anyone can silence me, please do!!! :D

Kev

I am having a brain block with this. My main image auto sizes just fine - 100x100 - 160x240 - 366x550
so hover works great

However my additional image sizes are too small

_01 53x80 - 53x80 - 53x80

_02 100x100 - 110x73 - 110x73

I'm think it's a Admin/images issue, but I don't know where.

Help would be greatly appreciated, Thanks

Thats an interesting one! When you hover over your additional image you can see that it is trying to display the large image file

images/large/MG15BMain_01_LRG.gif

Does this file exist? As when the image loads it is displaying

images/MG15BMain_01.gif (which presumably is the 53X80 image)

Kevin

I've taken another look at my site - my pages also try to load

images/large/xxxxxx_LRG.jpg and they don't exist.

That is when control gets handed to IH to generate an image and a picture from the bmz_cache folder is displayed. Your site still displays the images\xxxx.gif file leading me to think IH isn't getting the opportunity, or failing, to generate your image. Are all the files there? Are you folder permissions set correctly?

Could be to do with something in Configuration -> Images but that would be beyond my knowledge.

Kevin

Hello,

Firstly I would like to thank those responsible for Image Handler, it has been such a useful contribution for me.

I currently have the pop-up images activated and they look great, however I don't want the text indicating the product's name to appear above the pop-up image. Does anyone know how to get rid of it so that it is just an image that pops up when you hover over the small images?

If anyone could help me on this I would be very grateful as I have looked everywhere for this to no avail!

Many Thanks,

Tapellus

No bug, no patch needed.
This is the way IH works in the admin side.
If the true size of each image was to display in the row, it not would fit on most people monitors. Most people don't like to scroll sideways.
The image being displayed is the sample image to show that the file works, click on that row will now display the medium sized image to the right and then when you click that image the large image will pop up.

Can't get rid of it but you can hide it using the style sheet.
The how to has been posted in this thread.
Hint: search this thread for my name.

That is the size of the additional images you uploaded.

IH doesn't really like to up size images. This small of images will look really bad if they was up sized.

That is the size of the additional images you uploaded.
Yes, of course.
I put them thru an "optimizer". It optimized the h**l out of them.
Thank you Tophand

How can I increase the size of the hover image to 250px while keeping product info images at 80? Ive spend much time researching and cannot find the answer. I can see the larger image when I click on "larger image" but I want the larger image to appear in the hover too.

Thank you

Hi TopHand,

thanks for the explanation - it makes sense.

Do you know why the PNG file in the Preview tab does not display. The source file is there.

Rewrite the code.
Maybe start with the jscript.

Not really.
Had have trouble with 16bit/32bit png files.

Hi TopHand,
Thanks for your friendly and thorough response. I had searched the forums for several hours so I took your advice and rewrote the code.

Had have trouble with 16bit/32bit png files.
Interesting - but I'm using the samples included with the contrib. Will throw in loads of tracing to see where it is falling over.

Hi All,
I would like to change the size of my additional images without changing the size of the small images site wide.

In the includes/templates/mytemp/templates/additional_images.php from row 84-95 there is this

  for ($i=0, $n=$num_images; $i<$n; $i++) {
    $file = $images_array[$i];
    $products_image_large = str_replace(DIR_WS_IMAGES, DIR_WS_IMAGES . 'large/', $products_image_directory) . str_replace($products_image_extension, '', $file) . IMAGE_SUFFIX_LARGE . $products_image_extension;
    $flag_has_large = true;//file_exists($products_image_large);
    $products_image_large = ($flag_has_large ? $products_image_large : $products_image_directory . $file);
    $flag_display_large = (IMAGE_ADDITIONAL_DISPLAY_LINK_EVEN_WHEN_NO_LARGE == 'Yes' || $flag_has_large);
    $base_image = $products_image_directory . $file;
    $thumb_slashes = zen_image($base_image, addslashes($products_name), SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT);
    // remove additional single quotes from image attributes (important!)
    $thumb_slashes = preg_replace("/([^\\\\])'/", '$1\\\'', $thumb_slashes);
    $thumb_regular = zen_image($base_image, $products_name, SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT);
    $large_link = zen_href_link(FILENAME_POPUP_IMAGE_ADDITIONAL, 'pID=' . $_GET['products_id'] . '&pic=' . $i . '&products_image_large_additional=' . $products_image_large);

I changed the SMALL_IMAGE_WIDTH, SMALL_IMAGE_HEIGHT in both locations in this file to HEADING_IMAGE_WIDTH, HEADING_IMAGE_HEIGHT.

It works fine but it also breaks IH2 small image handling. They no longer pop up on hover.

I also tried SMALL_IMAGE_WIDTH/2, SMALL_IMAGE_HEIGHT/2

This works too but once again. . . broken IH2.

How can I do this without breaking the IH2?

Thanks in Advance,
John

I have fixed the problem of the broken page in the index now i have got another issue which is the category products do not open in the IH format. There si no resizing.
Please let me know why.
Thank you
