EZ thumbnails

Thanks for the feedback dinosoup,

dinosoup:

However, I found something, not sure if it's a bug or intentional. When I set "Image - Use Proportional Images on Products and Categories" to false in the backend, then EZ thumbnails does not seem to kick in.I took a quick look, and it seems like it's intentional.

This piece of Zen Cart core code in html_output.php disables the hook to external image handlers (like EZ thumbnails)

    // use old method on template images
    if (strstr($src, 'includes/templates') or strstr($src, 'includes/languages') or PROPORTIONAL_IMAGES_STATUS == '0') {
      return zen_image_OLD($src, $alt, $width, $height, $parameters);
    }
```And when the hook is disabled EZ thumbnails is disabled too.

Or maybe disabling the hook is an unintentional side effect (the formentioned code disables it indirectly). In that case it seems more like a bug after all. I don't know a good reason why external image handlers should not handle non proportional images. Maybe it's an easy way to prevent division by zero issues?? (when image with or height settings are 0)

If you know a little PHP and are not afraid to experiment, you can try what happens when you edit the zen_image() function to allow it to use the image handler hook even when the "PROPORTIONAL_IMAGES_STATUS == '0'".

Thanks for your reply paulm. I tried what you suggested, and no problem so far.

Anyone know if this can work with the "swap images on mouseover" mod

In the readme of this basic image handler I mentioned that someone reported that the script didn't handle the Zen extra images. But today I run a quick test on a fresh 1.3.7.1 install, and it looks like thumbnails of the extra images are created without any problems after all.

(I still don't use the Zen extra images myself, so I may be overlooking something.)

Hey,

First of all, your mod is fantastic, when it works. We get soo many idiotic clients using massive images for products. Really takes the pee.

Anyway, on to the 'when it works' part:

I upload your script to my server and it works fine sometimes. For some reason or other at times, the page with a certain image on acts as if it has had an 'exit;' function placed on it.

I carefully looked over which type of images cause this, but it's seemingly random. I've tried images over 3mb, some work. Some under 100k work. It just doesnt make any sense.

Very annoying!!

Your help would be much appreciated.

Works great.... At first my images would not show up the new products page. But after a minute or so and couple of refreshes..it works great.

@thomasharding: I can not reproduce the issue you describe, an url might help.

@Gamer: thanks for the feedback (and the images were probably cached by your browser at first).

Is it just me (I have a pretty bad flu right now) or do the thumbs look a little blurry when you use this script?

Can anyone comfirm this works in 1.3.8?

I've installed it, but it doesn't seem to generate the thumbs.

Thanks,
Doug

I just installed it on my testing server on a clean copy of 1.3.8 and on a modified live copy of 1.3.8 (No previous instillation of IH2). And it works great, thanks paulm. One thing I'd check for DougWare is that the images/thumbnails/ file has been created and can be written to. For easy use set Line 9 in includes/extra_configures/ezthumbnails.php to 'false' instead of 'true'. That could also be holding you back. After making sure all the folders were automatically created (loading every page I have, might be too troublesome for a larger site) I reset it to 'true'.

Hope that helps.

For easy use set Line 9 in includes/extra_configures/ezthumbnails.php to 'false' instead of 'true'.Yes. And probably you can leave it set to 'true', the reason that it's false by default is that I think it depends on the server if you actually need to set it to true. But it's more important to make the files and directories themselves unwritable again afterwards. Which is not typically related to this script, but just following a general advise as mentioned in Important Site Security Recommendations.

I fixed it!

I had to enable proportional images, which then broke my cart. I discovered that it was because apparently I was missing gd and php-gd. Now I'm good to go.

Thanks

Hi does any one know how to. or if its possible, to generate the ez thumbnails for any additional product images?

is there a function I can call? Or is there a bit of the code I can take and add to my additional images method?

All help/ideas greatfully received as this is the last bit I have to get working to finish my clients site and they are driving me crazy about it!

Hi,
I just installed, and have a problem. I'm not getting any thumbnail images, just the alt text. If I click the larger image option, I do get the larger image.
Any ideas?

Thanks:(

Have you set the permissions on the images/thumbs directory to 777?

Thats a rookie mistake normally :wink:

Thanks, that was it.
:lamo:

I've installed all the files as described and changed the folder to read write as suggested, however I still have no thumbnails being created.

I'm using 1.3.7 so it should work ok.

Anyone else had a problem with this?

Thanks

Actually I'm getting an issue right now with a client of mine..

Keep getting this warning message:

Warning: mkdir() [function.mkdir]: No such file or directory in /home/fhlinux148/f/finefossils.com/user/htdocs/store/includes/functions/extra_functions/ezthumbnails.php on line 64

Warning: chmod() [function.chmod]: No such file or directory in /home/fhlinux148/f/finefossils.com/user/htdocs/store/includes/functions/extra_functions/ezthumbnails.php on line 65

Scattered about the place. It's not creating the subdirectories for some reason and everything is chmodded perfectly.

The guy who I'm working with has created pretty much a subdirectory for each product, could this be causing an issue?

Thanks bud!

The script works on a default Zen Cart install and that also has images in subdirectories. Maybe there there is something special with the names of the subdirectories? Can you post or PM a link to the site? (edit: n.m., already found it, do not see why it would not work though)
