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

I have a watermarking question.

I see 3 options in the settings for small medium and large images to have watermarks : yes or no.

But what about the default image? We dont add "large" images we just have the main product image uploaded when the product is created and then image_1.jpg etc for additional images.

In admin I can see the watermark in IH3, but not on the live site.

So I think Ive misunderstood how the default image gets its watermark?

Is my question above valid or have I made a basic mistake somewhere? Any help appreciated.
Again, in admin in IH3 where you can see the product images, they are showing the watermark.
On the website you cant see the watermark and all images are showing from the correct place ie the bmzcache folder.

Regarding your question: After you turn on watermarking you have to clear the bmz_cache because IH needs to regenerate all your images again with the watermarks..

Hi thanks for the post.
Yes I deleted all the old files/folders and made sure permissions etc were correct.

I guess the question is, what do i have to do to turn on watermarking?
I see 3 options to turn it on, small, medium and large all have the option.
Ive set all three to "yes"
Is that all I have to do?

Yes turn on the watermarks you want (small, medium, large), then clear the cache so that the images are re-generated..

Ok thanks, next question.
Will watermarks ONLY work on images that have the suffix of _SML, _MED or _LRG ?
All the images on this site or any other site Ive used IH3 on just use the default image and have no suffixes.
EG

/bmz_cache/1/106a783492e3f3b6f699f848317889ad.image.700x604.jpg

Thats an image from the site thats a zoomed version, ie click to enlarge.

So its not small, medium or large, or is it....?

IH has NEVER required images to have those suffixes.. Upload the largest image, and IH will create the small, medium, and large images.. Please re-review the reademe.. all you want to know about small, medum, and large images is covered in there..

IH3 on 1.3.9 with new server and PHP 5.4.
Anyone else getting > PHP Warning: strstr(): Empty needle in /home/some_place/public_html/includes/classes/bmz_image_handler.class.php on line 129or > PHP Warning: strstr(): Empty needle in /home/some_place/public_html/includes/classes/bmz_image_handler.class.php on line 129

Like a few other users earlier in this thread, I noticed that Image Handler wasn't displaying the larger additional images properly, even after I upgraded to version 3 (maybe this is why the person who set up the site I've been maintaining ended up turning Image Handler off; I only looked at it again after someone else in the organization complained the preview pictures were too large): If the original filename were like images/product_01.jpg (for a product with main image images/product.jpg), it would try to load the larger image from images/large/product_01_LRG.jpg, even though the actual image would have been in bmz_cache, just like the larger version of the main product image and the thumbnails for main and additional images (which did show up correctly).

I got the impression, from reading this thread, that this issue had been fixed in Image Handler 4, so I decided to compare IH3 with IH4 and apply those changes that were not specific to Zen Cart 1.5 (things like better code quality and new defined symbols), and after I uploaded the changed version, the additional image popups finally worked; I plan to similarly backport the IH4 improvements into the default IH3 and submit that as an update (now if I could only set up an IH3 auto-patcher like the one in IH4...that's probably too onerous for me, though).

It's good that this tactic worked, because I had been looking at the code directly and not figuring out why the main product image popup referred to bmz_cache but the additional image popups referred to the old ZC-style path.

For the record, when I took over the store, it had Zen Cart 1.3.8 and Image Handler 2 (which was disabled) and some other mods (including Dual Pricing, which I figured out how to fix about 4 years ago on this very forum) that made it impossible to just copy over the core files from IH3 when I updated it (which was years after updating Zen Cart itself to 1.3.9h, and during this whole time I would just resize images by myself because I like manually optimizing product images to optimize bandwidth).

IH3, ZC 1.39h, Database patch level 1.39d, PHP Version 5.3.10-1ubuntu3.15, GD 2.0 with gif create, I'm getting the 500 error when trying to save the image in image handler.
The url causing the error looks like this: http://www.savorycajun.com/admin/image_handler.php?&products_filter=47&newImg=1&action=save.

I uninstalled and reinstalled IH3. My old images still work and look fine, but I can't use IH to upload new ones. If I ftp across the main product image into the images folder and set the image name in the product records, I can see it in the catalog and in the IH3 manager screen. It's just the upload that's doesn't seem to work. Hopefully, I've given enough information so someone can point me in the right direction.

I am using zencart 1.3.9 and image handler 3
I have been using this for some time, but today when I try and add images I am getting this error:
Unable to determine the page link!
Function used:
zen_href_link(",",'NONSSL')

I need help to fix this please.

I am using zencart 1.3.9
Zen Cart v139 was released in 2010. This is 2016.
YOU NEED TO UPGRADE. Things are changing in the way webservers (ie: your hosting company) operate, and your old version is not compatible with contemporary technologies. You are going to have more and more problems as time goes on, until you upgrade to a newer version.

I realize this doesn't give you a quick fix to solve the problem of "unable to determine the page link", but it needs to be said.

The "unable to determine the page link" message appears when an internal function tries to create a clickable link for you in one of your pages, but hasn't been given valid parameters. You may need to do a check on your server to ensure that nobody has hacked it and altered its files. Backups are a good idea.

thanks,
I checked with my server company and they said everything looked fine.
I don't know how to upgrade my zen cart. If I upgrade it will things need to be reconfigured?

Yes. Do the upgrade in a temporary separate copy of your site, so you can sort out any issues before you put it on your real site. Explained here: http://www.zen-cart.com/entry.php?3-How-do-I-rebuild-my-site-on-the-new-version-instead-of-upgrading

i got a stupid question,when i update zencart from 1.3.9 to 1.5.5b,i forgot to uninstall imagine handler,the old file still there,but i could not delete them because the page will go blank,how do i remove it complete?

I am trying to install this mod on my 1.5.5e store (the test version for now). I edited all the file names, uploaded all the files as instructed. I see the Image Handler3 under the Tools, and under the Configuration > Images, I also see all the new additional settings. Yet, if I go to Tools > Image Handler3, it says "No Image Handler information found." and when I click on Admin as instructed, nothing happens.

Now, I am wondering if it did install correctly or not. Since that mod works mostly "silently", how do I check?

Carole, you should use ih4 not ih3. This version is obsolete. When installed correctly, you will see the bmz_cache folder being filled with new image files, as you browse your site.> CaroleAs:

ImageHandler 4 can be found here

Ah! I searched for Image Handler, and since I didn't see the version 4 come up, I thought version 3 had a "latest version".
Thanks!
