Image Handler 4 (for v1.5.x) Support Thread

[carlwhat]

hi,
i have a site than is running:

Image Handler4 v4.0 for v1.5.x

the ZC version is 1.5.5 and the PHP Version is 5.6.19.

i have found a "problem", in that it seems IH chokes on a large file size and specifically in the function resize_imageGD. i have not tracked it down further as of yet.

the store owner uploaded a file that was 4.4 MB.

i have a few questions with regards to this situation. has anyone experienced this problem? is there any maximum file size? is it part of the server configuration or IH configuration? and finally, if it is a known issue, what do you think about adding some hooks for logging of this situation? ZC generated no logs, and i saw no apache error logs as well, which made tracking down the problem just a bit more time-consuming.

if someone has already posted about this situation and i missed it, i apologize in advance. and if anyone has any ideas about, i would appreciate it.

best.

There was a discussion started on page 143. I think was the same as your problem.

thanks for that. i have tracked it down to the function imagecreatefromjpeg. it should come back as false. but on my server, it just dies. i did finally get 1 error logged, with a memory size exhausted.

the problem is here, and considering the php function is just dying, i'm not sure how to even handle it:

	function load_imageGD($src_name) {
		// create an image of the given filetype
		$file_ext = substr($src_name, strrpos($src_name, '.'));
		switch (strtolower($file_ext)) {
			case '.gif':
			    if(!function_exists("imagecreatefromgif")) return false;
			    	$image = @imagecreatefromgif($src_name);
				break;
			case '.png':
			    if(!function_exists("imagecreatefrompng")) return false;
				$image = @imagecreatefrompng($src_name);
				break;
			case '.jpg':
			case '.jpeg':
			    if(!function_exists("imagecreatefromjpeg")) return false;
				$image = @imagecreatefromjpeg($src_name);
				break;
		}
		return $image;
	}

Did you also look at the server error logs?

[carlwhat]

i did. the apache error logs show nothing.... although i find apache error logs on shared servers to not be so reliable...

Yes, I have the same observation. Some errors will be logged to the root user (host) only. Probably the best solution for now is to tell the customer to use smaller image sizes , or a lower quality. Which won't make a difference for most end users, as they don't have a super high resolution screen.

As a suggestion, it's better to identify a post number instead of a page number since the number of posts/page is configurable based on your personal Zen Cart settings.

You are absolutely right. I totally forgot that was possible.

Hello
Super piece of addon software.

Just to be sure I understood what I have read :)
The standard zen cart product listing image is set at _MED.
This medium size image is not part of the standard IH4 zoom, if I want to zoom here I have to add a patch which is not seen as an ideal step?

HI,
I am testing this fantastic plugin in a test site. I wish I found about it before!!!! However I have a small problem. IN the main product page if I click on the image in order to see the large version, the image is loaded but the popup windows does not enlarge so to see the image you need to enlarge it manually. It is a 1.5.5a version.
I hoe thsi can be adjusted because I really love this plugin and I am ready to revamp all the images of the site. Thanks. Ciao from Italy. enzo
