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

Have you tried following my suggested resolution to correct your mismatched folder permissions?? Please give that shot and let me know if that resolves the issue..



As for the watermarking large additional images I have stated (repeatedly) that I will be taking a closer look at that as soon as I get home tonight.. It's not a showstopper feature(watermarking) and despite it not working as you wish, IH2's primary features should still function just fine..

I have not done anything to set these chmod permissions. :huh:

you'll need to run the install.. I suggest clearing the cache first (also in the IH2 admin)

but under the 'Manager' section everything is still visible, as if it were still installed... there's a disconnect somewhere.

I have no idea how it decided to think it's uninstalled, it was working fine last week...
I'm afraid to re-install it though, as it will delete all the work I've put into setting up each product.

I really need help from someone that's familiar with how IH2 works...
I can't risk anything without knowing what it will do first... this is a live store (that recently got a mind of it's own)!!!

Developers, feel free to contact me privately...
any insight would be appreciated though, I'm walking on eggshells here.

Thanks for the reply... but, seriously... wouldn't that just erase everything?

I've learned from experience that IH2 has a poor memory... so it's got me freaked out...
one wrong move, and it forgets everything except the first photo!

My store would be offline until I manually set 4 images on 400+ products...
here's a photo of how my IH2 is setup (that first photo makes things even more complicated):

I have thousands of people visiting the site each day...
my rent is paid, and my children are fed because of this business...
I can't just press a button and hope it'll work.

So are you sure I should delete the cache and re-install?

The mod obviously has NOT uninstalled itself (because that would be impossible)...
so I was thinking there must be a way to manually tweak this back to life in the database...
something just got knocked loose when I changed the category names.

I just don't know where to begin looking...

clearing the cache won't erase anything except the cache.. since IH2 is in an uninstalled state you'll have to re-install it.. and you should clear the cache before you do it so it can re-create your cache.. and you should backup your site before doing this..

Hi there,

I'm wondering if there is a fix to make Image Handler 2 work with private area. I tried copying the files from admin into the private area folder, but there is one file that wants to write over one in private area, and I'm worried that either one will not work after this. The file is: includes/modules/category_product_listing.php

Has anyone else asked this before - I did a search and didn't find anything, so anyone who can help would be greatly appreciated :D

Thanks,
Joanne

Not sure what you mean by private area, but you should use a file comparison tool like Beyond Compare or Winmerge to merge any differences between the category_product_listing.php files.

OK, never used that software before, but I will try - private area is a mod that scrapbooking stores use to isolate the designers areas, so only they can see and interact with their own part of the store. :D

Thanks!

OK, I would have NO clue how to merge the two files together :S

Anyone else have an idea?? lol

Thanks,
Joanne

I have a problem trying to upload a new image: I get this error:

Code:

---

Unable to determine the page link!

Function used:

zen_href_link('', '', 'NONSSL')

---

It's obvious what it refers to, but isn't the image supposed to come from my hard drive folder?

I did some additional checking of a few more client sites, and found that there were at least 2 sites where the permissions for the sub-folders are not being inherited from the parent as they should..

After speaking to their hosting companies I concluded that this is definitely NOT something the host is doing intentionally but rather something Image Handler is doing.. It appears that the IH2 code does this based on certain host settings. (in this case both of these sites are being hosted by Go Daddy reseller companies. The sites that do not have this issue are not Go Daddy hosting. (all various hosts)

So after doing some digging through the IH2 code I found a hint to the source of the issue. buried in the code is this reference to Tim's website: http://wiki.breakmyzencart.com/zen-cart:safemodehack

Now I gather that this was included to account for some server configurations where you had to set folder permissions to 777 to get Image Handler to work. (Which is how in the early days of Zen and IH2 it had to be done on many hosts)

Basically it looks as if one line in the includes/functions/extra_functions/functions_bmz_io.php sets folder permissions for sites hosted on some hosts to 777.

Code:

---

      return @mkdir($target, 0777); // crawl back up & create dir tree

---

this code on line 118 of the includes/functions/extra_functions/functions_bmz_io.php file is mucking up the sub-folder permissions for some (not all) webhosts.

Now I don't know exactly why on some hosts the permissions are inheirited correctly and on some hosts they are not.. I do know that if I change the 777 to 755, then the permissions for the sub folders created within the IH2 bmz_cache folder will be set to 755..

I am not entirely sure if this is THE fix, but it certainly is a solution. I would love it if ckosloff and clyde could weigh in to confirm all of this is in fact the correct solution, and perhaps shed some light on why it might work for some hosts but not others..

All the folders (0 - f) within that folder are also set to 755 and the files within these folders are set to 644.

Sounds pretty much like these new security concerns:
images in the bmz-cache are encrypted, so it does not matter to what security level they are set.
If you use some free security tools like the Hacker toolbar, a free add-on for Firefox, or even the Linux CD from backtrack-linux.org, you will see what I mean.
Try to find an entry point there.
755 works for most Linux servers, I don't know if for all.
Just to feed the paranoia you can set to 755 recursively your bmz_cache, IH2 does NOT set permissions for folders.
Regarding the coders, yes they are dead people, and bad too, addicted to forks.
However, the last incarnation for IH2 has been written and tested for Zen Cart simply because...there is no IH2 plugin yet for that other bad thing they indulge in.
But stay tuned and you might soon find one.
