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

[Crunch]

Adding on to my previous post:

I also just noticed a problem when viewing the test site on mobile (IOS using Safari or Chrome):

When you click the menu button (three horizontal lines), the page shifts over to the right to open the menu, but it's completely blank (White) with no items to click on.

This problem does not present itself when Image Handler is uninstalled. The menu opens just fine with items to click on.

Any one experience these problems noted in both of my posts?

These issues appear to be related to the lack of merging the changes of IH4 with your existing template before "installing" IH4. Note: generally speaking the files in the IMAGE_HANDLER directory are modified based off of a vanilla ZC install. The equivalent template files for your store are also in some way modified off of a default install, but the two are likely to be modified in different ways. You need to merge the pieces/parts needed for IH4 to do its business with the template file(s) of your site so that on installation you don't end up with the issues that you are explaining. The merge "process" is described in the IH4 instructions.

Thanks for the reply. I followed the new installations instructions, but apparently I misunderstood something. I typically don't have a problem with this stuff, but maybe it's been awhile. The way I read step 7 was that if I had customized the files listed in the table, then I need to make file merges. I have not customized any of the listed files, so I didn't do any manual merges. I then thought the auto-installer would take care of the rest. I am re-reading the instructions and it still reads that way for me.

By general process of working with the template *override* system, files generally should only exist in a template override folder if they are different (customized) than the default version of the file with the same name in the zc "core" area (template_default or each of the overrideable directories in the includes folder, etc.) so while *you* may not have written the code, the fact that such a file exists is a customization that has been "done" by you, by your direction (someone else), or by someone else before you were presented this store.

So, with that in mind, it would be advisable to merge the existing files with the IH4 so that when IH4 installs only the specific IH4 related code is "added" to your store.

Lastly, now that the above has been read. My apologies for using the word you so much. Was kind of to drive a point not to point fingers.

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;
	}

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.
