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

Most likely it is either a permissions error or an error with a corrupted .htaccess file..

Interference with an .htaccess file

If you have implemented .htaccess on your site, it may be interfering with the web page you are trying to load into your browser. Please double check the .htaccess configurations to ensure that it doesn’t contain any errors.
To confirm whether a misconfiguration .htaccess is the cause of the 500 Internal Server error, either remove or rename the .htaccess file temporarily and then try to reload the page.

Using your FTP software delete EVERYTHING in your bmz_cache folder and rename the .htaccess file (remove theleading "." and rename it to something like htaccess.txt)

Check your folder permissions for the bmz_cache folder.
Check the permissions of the folders/files IH3 generates within the bmz_cache folder. If there are permissions error you may have to work with your hosting company. (See recent posts here on this matter)

Hi guys

I'm experiencing a 500 internal error with my site caused by this module. Products prior to this module are working correctly.

Also my admin/image_handler.php page is blank (500 internal error page). I have gone through the readme again and usage instructions and can't spot anything I've done wrong. Have reuploaded this file and its still the same, I'm guessing my problems are stemming from this.

Any ideas??

Working Link: hawaiian-shirts.co.uk/hawaiian-shirts/blue-surfing-in-hawaii
Error page: hawaiian-shirts.co.uk/hawaiian-shirts/ <-- doesn't work as it includes new products which have error.

This also caused a 500 error on the front page as it displayed new products, I've had to remove that for the meantime.

Thanks.

EDIT: Btw, no error logs in /cache or cpanel error logs and my /bmz_cache contains files/folders

Thanks for looking into this for me. I've tried as you suggested and deleted everything in bmz_cache and renamed htaccess but still no fix. Contents of bmz_cache are coming through as CHMod 755 --- would that cause the 500 error?

try chmodding it to 777 and see if that helps

Are you sure that you put all files into their proper places and used the one that is common for both lightbox/ih3 (using the one from lightbox v6

I was wondering -- at first I thought lightbox was not working then I see that the image is huge...is that your intention or did you not set a size in its configuration too.

[AshleyNG2]

I've chmodding the folder and all containing files to 777 but it still did not make a difference.

I do not think its an issue with lightbox as it also caused a 500 internal error on my front page when products which have had its images through IH are shown in the featured products box.

Regarding the HUGE images, that was what they were uploaded as, IH would have solved this using the sizes I specified in the config but as I've disabled it for now (until this is resolved). Will have to manually edit the images if I can't solve this.

Thank you for looking at this too!

1)
No, Image handler is basically a php script, most people don't upload massive image over a megabyte (the images you have are photographic quality not web optimised), in all likelyhood image handler is choking (timing out) on the sheer size of the images/ one of your images is 1.3 MB (1,305,878 bytes) in size,

Basically what you could try is, saving those images for the web normally that would mean they are about 10-20% of the filesize but they still look the same on a monitor.

Image handler will create all 3 sizes but the problem is "possibly" that the raw file is so big that the script is timing out before completeing.

This does happen ocasionally and it is normally down to either really large raw files or something corrupted

2)
What version of Imagehandler are you using, and what version of Zencart?

3)
Did you get the admin/imagehandler.php page working, because this is where image handler is installed from, and from what you say you seem to have installed it

4)
What errors are showing in the /cache folder in the rot of your site
note the errors will be in the /cache folder not the /bmz_cache folder

please try checking once more to see that all files for IH3 were manually uploaded to their correct folders.

then go to admin/tools/ih3/admin link and not only clear the cache but uninstall it. then install it again...sometimes that helps.

I have 1200x1200 images in some spots in my store and they even without ih any version at the time were showing properly in the light box window...may be a setting that is wrong cause there should be no 500 error if things are cmodded and uploaded properly...

you might even while checking reupload the files one at a time again...they sometimes get into a web hiccup and corrupt just a bit.

I don't know if this is same problem I had back in IH2 - the chmod settings I was using were creating errors because they were at odds with settings my server required for security reasons.

At the time I found this code modification of admin/includes/ih_manager.php

http://www.zen-cart.com/forum/showthread.php?t=35913 reply#3809

Merging the 3 chmod ref bits of code resolved the conflict for my situation.

I carried those changes over to IH3 when I upgraded. (I confess I did not try IH3 without those changes.)

That was not much pretty with these big ugly red words, but whatever.

So, about your comments:
1. how can I post a link to my admin page? :)
2. on screenshot, there are IH version, ZC version and oh, of course, the fact, that it is an admin page...
3. Options in Configuration->Images are affected only on eshop pages, not in admin page (maybe I am wrong).

there is a problem with IH resize image, that posted AshleyNG2 (I disabled this option and images now displayed on product pages), but not in admin page.

soxophoneplayer: I tried, but no effect.

Since none of us can see the backend files that make up your store we can only help troubleshoot based on what we can see (your store).. A screen shot of your admin doesn't really provide any information. There is a LOT that we can acertain from seeing the site.. Without a link to the website where you are having the issues at it's hard for us to GUESS at what the issue might be... So the information we ask for is to help us help you..

My test site: http://www.syva.sk/eshop_test/
When I disabled IH resize image option, images are displayed on product pages, but not in admin page. Also, when this option is set to NO, images zoom on hover doesnt work.
