Hello Arno,

Sorry to be such a difficult user. After reading your most recent reply I decided to look a little further. I looked the example that I referenced in the original message and discovered that even though I chose the “scaled” image to use in the Lightbox, when I looked at the actual image that was in the Lightbox, it was the “Original” image (lacking the caption), NOT the “scaled” image. I’m not sure how the actual image to display in the Lightbox is chosen, but in your example above, it was the scaled image; in my example, lacking the caption, it is the “Original” image displayed, NOT the “scaled” image that I chose to be there.

Also, I noticed that posts I created before January 2022 display the caption correctly in the Lightbox and display the “scaled” image instead of the “original” image. Posts I create now refuse to display the “scaled” image, substituting the “Original” image in its place. I dried several different images that were scaled when uploaded. Posts written before January 2022 display properly but posts written now do not.

When I got back to my web site in January, after several months of delay, I found updated to WordPress, Jetpack, themes and your Lightbox plugin. I’m wondering if some of those updates could have caused this problem? I noticed some new checkbox options in your Lightbox.

I am a novice with WordPress web design. And, I do not want to take up too much of your time with this problem. However, if you are willing to guide me a little bit, I would be happy to take your lead on experimenting with it to see if there is a solution.

Thanks much for your help and guidance.

Later…….. Tom

Thanks for your reply, Arno. I temporarily solved my problem by reducing all my new images to a 2560 pixel long edge with a post process (interestingly, this problem does not exist with my previously uploaded and used larger images?). Unfortunately, the camera app I use with my iPhone creates a 5MPixel image with a 2492 pixel long edge. There are apparently three standards recommended for a 5MP image,
– 2560 x 1920
– 2576 x 1932
– 2592 x 1944
They chose randomly because it was the largest. I contacted the camera app vendor about this problem and they agreed to change their size to the 2560 long edge. That eliminates my need to post process the images, but it would be nice to not have to worry about this in the future. It’s likely other users may run into this problem sometime as well. Please let me know if you find a solution.

Thanks………… Tom A

Hello,

I was trying out Jetpack Carousel today and noticed that the image captions are not displaying on my iPhone. However, they are displaying on my iPad and iMac. Something seems to be amiss for the mobile version. This report is labeled RESOLVED. Does anyone know what the resolution is. I can’t use the carousel until this gets fixed.

Thanks………… Tom A

Hello Arno. I am back after a couple of months working on my web site again. There have been a lot of updates to WordPress and all my plugins, including “Lightbox with Photoswipe”. Everything seems okay with my existing posts using “Lightbox with Photoswipe”, However, now, when I upload new image files for use in a post, any image that is larger then 2560 pixels on one edge will be “scaled” by WordPress and then will not show it’s caption in the lightbox. I found this explanation about why my images are scaled:

Introducing handling of big images in WordPress 5.3

I noticed that you have made a lot of changes in the lightbox code. Any idea if the changes might have affected its ability to display the caption on my “scaled” images?

Thanks for your help. -Tom

I deleted and replaced the 5 files that wouldn’t show their captions. Wala! The captions now show. I also noticed that if I uncheck the option “Get the image captions from the database (this may cause delays on slower servers)” the Lightbox reverts to the original problem of no captions and small size.

So, things are working well now, with all the fixes. Thanks so much for your help, Arno. Hopefully Jetpack will get their act together on that tiled gallery sometime soon.

I did some additional testing (with 3.2.8) before you updated to ver 3.2.10. As it turned out, I turned on the Jetpack “Enable Site Accelerator” and then turned it off again and it tripped something in the code (?). After that, the sizes were all showing properly as long as I had your new box checked. Without it the sizes were reduced. So size now works with your fix.

With version 3.2.10 The captions are still operating the same. They show with your fix only and 5 of them are still missing. I checked for the captions in the media library and they are there. I even looked at all 8 of the various file sizes that were created in my home directory and they all had captions imbeded. Those 5 have a different naming system. When I uploaded these 5 they were very large images (over 1.2 Meg) and were downscaled on arrival. In the Media library these 5 images file name is subscripted with “-scaled” instead of the original name. Somehow, this has caused the captions to not show in the Lightbox. Maybe the captions are stored in some other database or something? This gets beyond my skillset.

While I was poking around in Jetpack I turned on their Carousel option. It projects a full screen lightbox for the Tiled Gallery but with many fewer options than “Lightbox with Photoswipe”. However, the 5 pix with the missing captions showed their caption in the Jetpack Carousel lightbox.

At this point, “Lightbox with Photoswipe” is working well with your fix except for a few of the captions. I’m not sure where to go from here other than wait for Jetpack to fix their bug or try to download smaller replacements for the few large files that are not showing their captions.

Thanks a lot for your help.

Thanks for working on this, Arno. I tried the new version and it does now show the captions, but not on all of the photos. Some of the captions are still missing. I’m not sure why. I did notice that on the correctly working posts (pre Jetpack update) some of the images use a file called “image-scaled.jpeg” instead of the “image.jpeg” file. This might be because the original uploaded image was very large and exceeded some upper bound? Not sure if this is why some of the captions are missing?

Also, the images are not enlargeable, like the others. They are still fixed at the 1024×768 standard size. Turning on or off your new setting does not affect the size. Was it supposed to? hummm……. I wonder if Jetpack is working on a fix?

Thanks for your help.

Gosh, Arno. You really are on top of this. I’ll definitely notify Jetback about it, too. Let me know if you find a work around, but I hope a solution ultimately comes from Jetpack.

Thanks………… Tom A

Thanks so much for your “lightning” reply. I understand exactly what you are saying. I did choose to “link to the media” in the option in the post setup as instructed. However, I chose the pix from the media library exactly the same way as in the earlier posts. As far as I know they were the only options available to choose from the media library and those options did have the captions. I wonder if there is something “new” going on, like Jetpack or Astra linking to a smaller copy of the photo from one of their servers, to provide “faster loading” but mucking up the situation in the process. Hummm……

I’ll circle around and see if there is anything like that operating in my site. This is very helpful. Thanks so much for your analysis. Please let me know if you have any other thoughts or ideas.
