Image Handler 3 Support Thread (for ZC v1.3.9)

[ScriptJunkie]

Zen Ver 1.3.9h
Image Handler version Version 2

When someone is using Firefox (ver 7.0.1) images cannot be enlarged without having to play around with the mouse. For example, if you open a product on my site below, try to click on the image. Note the mouse icon with not change to a "hand" unless you center the icon in the middle of the image. SO most customers assume the image can't be enlarged after clicking their mouse a few times and nothing happens.

What you're talking about can be found on this product page.

However, when other images, such as those under "We Recommend" found on that same page, or those found under "New Products" on your home page, are moused over - IH works exactly as expected. Which is to say the image is zoomed on mouseover.

The issue you are describing (and which can be reproduced by me when I visit your site), is not an IH2 or IH3 issue. It is an issue with FF 7.01 and ZC's core functionality as it relates to viewing a larger version of a product image when on a product info page.

The reason I know this is because I know that the functionality of ZC which enlarges product images on click is not a function of IH2 or IH3 - it is a core ZC functionality that remains unchanged by IH2 and IH3.

IH does not handle the zooming/enlarging of product images on product info pages because IH does not handle medium size images - and ZC uses the medium size image to enlarge product images (on product info pages) on click. This is addressed at length in the IH3 Read_Me.

Seconding what Diva has said, suggest you take this up with FF developers and/or in the ZC forum on the general issues board. It has been suggested that the FF issue is really an issue with an addon called Firebug, but I use that addon and have no problem on my site.

The issue seems to affect some stores while leaving other stores unaffected. Whether it's a FF issue, a Firebug issue, an individual store issue, an outdated JS issue, or a browser permissions issue...it is clearly not an IH3 or IH2 issue and therefore should no longer be discussed in this thread, as it could be confusing to new Zenners.

Good luck and happy Zenning

Hi, I'm using 1.3.9h - I have IH3 and Lightbox installed - I have 2 problems that I would appreciate some advice on

Error!

Unable to determine the page link!

Function used:

zen_href_link('', '', 'NONSSL')

I get this error when loading images to a product.

Firstly I cannot load an image in product page (add new product) - just will not load. When I use IH the images all show up however an error message says "cannot upload default image" - then when I save I get the above message as well. All images except the default image show up in the catalogue online - where the default image should be is the text for the image and the "click for larger image"- clicking on either of those texts brings up the image.

I have uninstalled and re-installed both add ons a few times but no change.

Any ideas please?

many thanks,
Mike

1) read through the thread, that error message has been discussed many times, 99% of the time it means you are using invalid characters in image file names, which cause image handler to choke. The image handler documentation and zencart documentation both explain what the invalid characters are, but basically stick with alphanumerics and dashes and underscores and you ahouldn't get that problem.

2) What size are the images you are trying to upload, some servers may timeout if the image takes to long to upload

Thanks Kiwi,
images are only small (20-50kb .gif files) and server time out is not an issue and no special characters are being used - images were all loading fine before I installed IH3 - not even sure what advantage IH3 is given that 1.3.9h resizes images in any case? Having said that I do not think it is an IH3 problem - something is preventing the loading of ONLY DEFAULT image to the product page period. As a stop gap I have been inserting the default image by using EXAMPLE <img src="XYZ.gif" alt="ABC" /> but even that now will not produce an image on the product page - it will show however the "alt" description.

Does Google Merchant "use IH to resize images" true / false have any effect - seems the issue started when I loaded Goggle Merchant Feeder. Do any other Image Configs conflict with IH3. I no longer name images with suffixes (_MED, _LRG). Bit of a head scratcher.

cheers,
Mike

Umm 1.3.9h doesn't resize images, by default it sends the fullsized image through to the browser with instructions to display it at a small size, image handler reizes the image then sends it to the browser at the specified size.

without looking at your site we can't tell you, have you

a) checked your /cache folder for debug files
b) made sure that you have installed all the imagehandler files, and renamed the "your template" folders in bothe the templates and modules directories to match your template name, (honestly the number of people who believe that putting up only half the files will have no effect is a bit suprising),
c) tried installing imagehandler by itself, without lightbox and seeing if it works correctly
d) Is the problem in the front end(shop) or backend(admin) of the site
e) Are you sure imagehandler is handling the images, right click on an image in the store and see what its name is.

I am still in the learning process of Zen so be kind!!

In the install instructions it says to:

Upload the files from "1_Install_Files" to your store. (DO NOT upload the "1_Install_Files" folder, just the CONTENTS of this folder -
copy ALL of the add-on files to your store!! Most issues are caused by store owners who decide to NOT load ALL of the module files)
Upload the files from "2_Required_Core_Edits" to your store. (DO NOT upload the "2_Required_Core_Edits" folder, just the CONTENTS of this folder - copy ALL of the add-on files to your store!! Most issues are caused by store owners who decide to NOT load ALL of the module files)

If any of the files in the "2_Required_Core_Edits" folder have been modified by other module installs, you will need to use a file merging program like Beyond Compare or Winmerge to incorporate the Image Handler3 changes

My question is this:


1. What keeps these folders from completely overwriting the original folders in my server?

2. Am I uploading to the /directory of my store?

3. How do I know if files in the "2_Required_Core_Edits" folder have been modified by other module installed?

Thanks for your help
