I doubt this is a skin error but thought I might get the quickest answer here.

I recently rebuilt one of my albums after a good bit of time and received the following error on numerous (not all) jpg images ... same error attached to each of the offending images.
javax.imageio.IIOException: Metadata components != number of destination bands

Never received this error before so not sure what/why I'm seeing it now. I haven't looked closely at each of the offending jpgs but many were originally scans of family photo albums done by one of my relatives so I'm not certain how they were scanned/processed.

I don't have access to the original photos so re-scanning is not an option. It might be possible to open each image in a decent photo editing program and then resaving them as a "new" jpg file, possibly cleaning up any hidden issues. I haven't tried this yet since it would likely be a slow process. A simpler, faster solution would be preferable.

I'm using a Mac Studio with the latest jAlbum/Neptune updates.

I should have included more info ...
The album giving me fits is the Family album of tuband.com. I recently took everything down since I'm doing a major reorganization of the tuband website. Didn't really change anything in the Family albums but discovered the issues in the Jones album. Open any of the sub albums to see the missing thumbnails. Clicking on the missing space sometimes (not always) opens up the larger image. I think every sub album is affected, some more than others.

I've attached 2 files - same image handled two different ways. Scanned at the same time as far as I know. One works, the other doesn't. To look at them on the website go to jones/warren

We're currently having a thunderstorm as well. Doesn't seem too bad but giving some much needed rain. I live in the foothills of N. Georgia mountains, about 20 minutes from the southern starting point of the Appalachian Trail.

will follow your suggestions & report back - probably later today. Thanks.

I do love it when a hunch pays off.


No. In fact, when you choose that option, jAlbum warns you that it might be ugly.


You might be offering the images for downloading, and want to preserve things like the original camera information (exposure, aperture, etc.) or the GPS coordinates. Facebook, for example, strips out all of that stuff, so if you save someone's photo from a Facebook post, the original GPS info is, sadly, gone. So, you end up having to ask your nephew which mountain peak the picture was shot from.

What made me think that might be the problem here was your mention of scanned images. Scanning software often doesn't handle the metadata properly. After all, there's no "camera" info involved, anyway. But that does mean that attempts to write out metadata to the generated slide images can result in some pain. I noticed, for example, that a lot of your missing images weren't actually missing the files - the files were there, but were mangled beyond usability. When you're debugging, this is what's known as "a hint."

Even tho I don't remember checking the metadata box I must have done so since I use the GPS info for the maps option. Odd that the errors did not show up earlier.

The Family albums have only one sub album that consists almost entirely of scanned images. The other Family albums are photos that don't produce the error. Is there an easy way to isolate the single album with scanned images to prevent the errors but keep the metadata in the other albums? If not, I can copy each scanned image and save it as a new jpg image or leave the metadata out of all the images and not have GPS in the other albums.

thanks for the clarification
