    Default Re: Image Handler 5 (for v1.5.5) Support Thread

    I need to ask a really stupid/newbie question. I've tried reading FAQs and the github page, but I can't find anything that answers this directly.

    We have a site with thousands of images already posted for products we sell. If we were to use Image Handler, would I have to go back and assign an image via the IH interface for each product?

    Nope, IH's image-resizing occurs on-demand using the base image defined for your products and any additional images that are present.

    What happens is the image you have defined in the admin for that product gets used for creating smaller images the first time a customer views that product.
    These smaller images are stored in a cache.

    Additional Images
    If your defined image is /widgets/product001.jpg,
    you put the additional images in the same folder and name them with an underscore:
    product001_somethingelse.jpg
    product001_moresomethingelse.jpg

    and they will be handled too, automagically.

    You don't need to ever enter the IH interface to assign anything. In fact, after 10 years I still don't know what that admin IH stuff is for/never used it!

    when the images load on my website, the picture quality for the 'large' image seems blurred, is it possible to adjust the compression settings?

    been searching the configuration section, nothing i can tweak to adjust the image quality.

    In Configuration->Images, once IH is installed, there are 3 configuration settings (one for small, medium and large) for image quality: https://github.com/DivaVocals/zen_Im...es/c_images.md

    Did you, by chance, update IH from a previous version of Image Handler or was this a fresh IH install?
    This bug is occurring again after I installed into ZC 1.5.6a (with upgraded database from ZC 1.5.1)

    While the above SQL solved problem, but I have to reuse that SQL each time I try to reload the database for testing, which is quite rather nuisance...
    Wonder what happened in the install progress, which lead to notice *stuck* in admin.

    I decided to be bold and check database...

    Interesting is that, there is absolutely NO SINGLE VALUE with IH_VERSION on either of databases! (Both the current production database of ZC 1.5.1 and the upgraded testing database of ZC 1.5.6a)

    Here is what is on IH configs on ZC 1.5.6a database...

    Why is it not installed as part of upgrade or something?
    This is surely a bug or something because it seems I will have to keep using the SQL patch each time I reinstall IH5!

    UPDATE!

    The SQL fix is now no longer working! I changed value to '5.1.2' to match current version and the notice still above the admin page!
    Also, the "Previous Product" button is underneath the "Product Listing" dropdown!

    Thanks for that; it helped me to "see" the root cause of the issue.

    What's going on is that many of the previous Image Handler versions didn't include an IH_VERSION constant, so I'm currently checking for the presence of IH_RESIZE to identify a previous install. Unfortunately, those conditionals in the install/upgrade processing don't account for that fact.

    I've created a GitHub issue to track the correction: https://github.com/DivaVocals/zen_Im...ler/issues/151

    I've just pushed a change for that GitHub issue, if you'd like to verify that it corrects the issue that you reported!
