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

I have a problem with the creation of png's. All images that ImageHandler creates that are .png are broken. As far as I know I have setup ImageHandler correctly and it does fully work for other filetypes.

Even on my new virtual server this does not work. So any cached image that ImageHandler creates and that is an png is broken.
The png's that where created a few months ago on my old server are all broken to. So I don't think its some missing library or so...

I have installed libgd and ImageMagick:

dpkg -l|grep gd
ii libgd2-xpm 2.0.36rc1dfsg-6ubuntu2 GD Graphics Library version 2
ii php5-gd 5.3.10-1ubuntu3.4 GD module for php5

dpkg -l|grep imagemagick
ii imagemagick 8:6.6.9.7-5ubuntu3.2 image manipulation programs

Here is one of the broken images:

http://www.snelwebshop.nl/bmz_cache/a/ad5b68fddb7a62c955b59d70a322a0c8.image.55x40.png

If I download if via FTP and test it on my local PC its also saying that its damaged.

For now I have setup ImageHandler to convert all images to JPG... but I would love to use PNG again :-)

Any idea on why this is going wrong?

If this is for Image Handler v4, then you need to post in the IH4 support thread.. You also need to check your source images.. If they are damaged then IH4 will created damaged files from these damaged images...

This is an Imager Handler V3 (installed on Zen-Cart 1.3.9) so this should be the right forum :-)

I recreated the png with photoshop... still gets the same damaged images.

When I have time I will install the latest version of IH to check if that fixes this issue.

I doubt that IH4 will solve the issue.. It sounds to me like the issue is with your source files.. If you are "creating" these images within Photoshop something in this process is creating a file that is corrupted/damaged. In any case the issue is not Image Handler, but something to do with your source images..

Not its really something with my installation of IH (of something else). I just used an png that I downloaded from internet (some picture of the movie Brave). Same problem!

The strange thing is that is goes wrong on my old server at home and now again at my new ubuntu vps server...

I'll do some more testing to figure out whats causing this problem.

Since this is not a commonly reported issue, it's more likely that the issue is specific to your server (again NOT an IH3 issue)..

If you are happy with working through shell you should be able to scale a test image using either imagemagick or GD. If you aren't happy with shell or don't have shell access then you could write a script to do it. There are pages and pages of instructions on how to do both these on the web. I'd do that first and see if your server is chewing up the images. I am not saying that it is but it would be a good idea to prove to yourself that it is not.

I'd guess that just upgrading to IH4 is not going to make a whole lot of difference because I do not believe ( not 100% sure here ) that the code that actually does the scaling has not been changed for a while. Bits around that core have been altered, but not that core - I believe.

Sorry not to be of more help than that but as Diva says this is not a widely reported issue.

Hi,
I have followed the first four steps of the readme installation instruction.
The next step where I should copy the files from "1_Install_Files" to my store i have two queries:

1. The site is live so "my store" would mean "public_html" folder, right ?
2. The public_html folder has a folder called images, so when I tried to copy the folders i got a prompt saying images folder already exists.. should i replace the old folder? It has lots of images of the products i sell. Will they all be gone?
   Apologies for the naive question but if I overwrite the images folder where will IH3 get the images to work on?
   Thanks

sorry I hop a problem with image handler ... how do I make it appear on facebook preview the product and additional pictures? I'm going crazy: (

Post this question on the Facebook module support thread.. IH4 is meant to manage product and category images.. I have no idea how your Facebook module works..

When you say the images folder---are you trying to upload the entire images folder from the zip???

IF you are then yes the images you have on the server will be gone. You just upload the contents of the zipped folders NOT the entire holding folders, those are there for you to know where those items go...

images/large/its contents go into your store folder/images/large folder and so forth.

If that is not what you meant sorry.

If that is not what you meant sorry.This is NOT true.. you will NOT wipe out the contents of the folder.. The prompt is because it recognizes that you are copying over a folder of the same name.. Saying yes will NOT wipe out the CONTENTS of the folder.. You will simply upload the content that does not already exist in the folder.. Test it out for yourself to confirm what I am saying..

Unfortunately many older or free FTP programs do not use accurate user messaging, giving folks the impression that uploading a folder of the same name as an existing folder in the target location will replace the folder in the target location. This is in fact NOT what will happen.. In my previous message I included a screen shot of my FTP program which has a much more accurate user message which more accurately describes what actually does happen if you upload a folder where the folder already exists in the target location..

Thanks!
This explains a lot.

Thanks !

Hi guys

two questions :)

What is the best size image to upload for IH3 , currently I'm using 800x600 jpeg . What would be optimal for IH3 ?

Also when I click on 'Larger Image' a browser window opens but it is very small. I have included a picture below . Is there anyway I can change it to open a larger popup ?

Thanks Paul

You can upload any size you like.. the issue with your popup looks like an installation issue..

I had problems like that with 1.37 and fixed it with the stylesheet but I surely can not remember what I changed, sorry

but on the other hand you could install zen_lightbox and not worry about that...lol it works great with IH3 especially if you have additional images too

The small popup still points to an install issue and it's unlikely it's an issue with the stylesheet. I would bet there are errors in the error log which are causing the popup to fail to render correctly..
