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

[thedust2010]

OK, I've started over with a clean install of Zen-Cart 1.3.7. I then install Image Handler (no other add-ons), and it won't work. When I look at the preview page in the admin I get this:

Warning: imagepng(): Unable to open '/var/www/vhosts/thissite.com/httpdocs/store2/bmz_cache/8/830c17d7e3dbdc37ccf193cb68df5818.image.150x84.png' for writing in /var/www/vhosts/thissite.com/httpdocs/store2/includes/classes/bmz_image_handler.class.php on line 647

Any ideas? I just think this doesn't work with Zen-Cart anymore because we've used it plenty in the past with no problems.

I've gotten this issue working but it appears Image Handler doesn't work well with Ultimate SEO URLs anymore? That seems to be the problem... though we've used them together before with no problems...

Well, wrong again. I've got it working with Ultimate SEO URLs. It's now in a state where I have:

Zen-Cart 1.3.7 installed
Image Handler 2 installed
Ultimate SEO URLs 2.105 installed

Individual product pages work fine under any conditions until I install Image Handler. At that point a blank page is served up. No errors, no source code.

Can someone confirm that Image Handler is working with the most recent version of Zen-Cart? We've never had these issues before.

I just discovered the issue:

Admin > Configuration > Product Info > Previous Next - Navigation Bar Position

This needs to be set to 0 (off). Otherwise Image Handler displays a blank page. Anyone know why?

Quick question. Can I change the size of my medium pictures or can I change the roll over image to be my large image? Either one would work for me ... but I can't figure out how to do it.

Setting up a new site and have a couple of questions...

1. I want to keep all my filenames lowercase for sake of uniformity. are there any problems I might encounter with this choice?

2. I noticed if I have a large file (say 100kb), even after IH2 resizes it for me into the bmz_cache folder, the 100kb file will still exist in the original directory. Is it therefore recommended that I first resize the 100kb file smaller into say my desired resolution of 400x400, then upload to ZC and let IH2 do the resizing?

Hi evrbd,

Firstly I would like to say that this forum is really helpfull.


I my second Zen shop IM2 works OK, but in my first I got a problem.

In preview in HM2 configuration menu I recieve following message:

Warning: imagepng() [function.imagepng]: gd-png: fatal libpng error: zlib error in /includes/classes/bmz_image_handler.class.php on line 646

Warning: imagepng() [function.imagepng]: gd-png error: setjmp returns error condition in /includes/classes/bmz_image_handler.class.php on line 646

And all images are not showing. When I try to and picture to product I get following message:

Unable to upload default image file.

Please - help :)) (nothing extraordinary)

No that will be fine.

2. I noticed if I have a large file (say 100kb), even after IH2 resizes it for me into the bmz_cache folder, the 100kb file will still exist in the original directory. Is it therefore recommended that I first resize the 100kb file smaller into say my desired resolution of 400x400, then upload to ZC and let IH2 do the resizing?

My advice is to resize your images to the maximum size that you want displayed. So if 400x400 is the maximum size you want on your site, then resize all your images to that size and upload them. Image Handler will then automatically create small & medium sized versions from this according to the sizes you have specified in zen cart.

I've got a feeling I have just confirmed what you were going to do anyway.

[kai920]

scenic, did you see this on the documentation?

Requirements

In order to resize and modify images, Image Handler 2 needs either GD libraries (since version 2) or ImageMagick (since version 6) installed. You can check if your version of PHP includes the GD libraries by going to Admin → Tools → Server Info and searching for GD. You have to ask your host (or read your site’s documentation), to learn about an ImageMagick installation. If you want to render GIF images, you need to have GD libraries version 2.0.28 or newer installed.

Craig, yes , indeed that is what I am going to do. thanks for confirming I am on the right track! :)

I just recently updated my cart from 1.3.6 to 1.3.7. Image handler is installed and working. Except that the extra pics that are supposed to show up at the bottom of the page are not showing up. They are shown in the IH admin, but not on the product pages. Any thing I'm missing that I need to do? Thanks! Amy
