Recreating specific thumbnails and resizes

Can anyone recommend a reasonable way to recreate thumbnail and resize files.

During a 1600 picture load and subsequent bulk movements to other albums, a number of the pictures don't show up, just the filename, in the thumbnail view and resize view. Since the database had the correct entries, I just directly copied over the missing fullsize files into the correct album folder, hoping to 'con' it into getting fixed when I ran the Rescue module. No joy.

Are the 'Dirty' indicators in the database the best way to do this??

Before making any change, I went to the Maintenance panel and noticed that I had 7 out of date photos that needed rebuilding. So I figured I would get these done and out of the way so as not to complicate matters later while testing.

I clicked the Run button and the screen grayed and popped up the alert that it was starting, but nothing happened for about 10 minutes, so I clicked the Pause button.

On the list of Maintenance tasks, there were TWO entries with a Status of Stalled. I clicked the first one to Resume, but it did not seem to make any progress, so I clicked the Pause button again.

An additional Stall indicator did NOT appear, just the original two. So I cancelled them both and for the resulting Finished Tasks, I looked at the log for it as follows:

Note that it seems to be spawning off two attempts to run the task. I wonder if this is creating some form of interlock with a file or database row?

The previous rebuild attempts are on hold for now!

I think there is more going on than meets the eye.
I copied off all of my /albums in the var folder - just over 12000 fullsize pictures.
Then I reorganized then all under a single Gallery folder and several subfolders etc.
I gutted my installation (and database), reinstalled G3B3 and the latest exp version.
Then I added my new Gallery folder as a valid source for the Server Add function and fired
it up. It as about 3500 pictures strong and has been running about 9 hours.

But using another browser, I looked at it and it all seems nice and neat except that one of the subfolders is
now located under the wrong top folder/album. During all this time I had been using the
system to re-organize the albums that had already been completed, marking them to show by date captured etc.
My guess is that some small conflict occurred and was mishandled, causing the subfolder/album to get inserted
into the wrong top folder.

That mass load I started yesterday STALLED sometime during the night at just under 8000 added. Tried to pause and resume it but with no luck. Managed to track the last picture dowm - It had three thumbnails shown in the album with NO picture image. I deleted all three and tried resume again with no luck. Went into the items table and found the last entry added (still had thumb and resize dirty flags set). I deleted that entry, removed the source picture and this time the Add picked up and started running again.

Attached is the 'problem' picture - be aware it is about 2.4MB in size and is 6015px wide by 8569px high with 1200 dpi resolution.

OOPS - max upload size is 1mb - what next without risking changing the contents.

(Edit) Just tried to upload that picture via web. Attached is the result - a bad format error that made it fail, but also the net result is a database entry for it that shows up as an empty thumbnail.

Try it again. I forgot to disable the hotlinking block.

Dave,

It did not come directly from a camera - it was scanned in and then I used Exifer to set the dates/time and thumbnail into it. I have done this for all my old pictures without problem.

But this one was much higher resolution at 1200dpi and I think that this is the major cause of the failure when loading it. In fact, I did the same thing over but scanned it at about 300dpi, added the stuff with Exifer, and was able to load it in without problem.

If you have a way to reduce resolution without destroying the exif data, try it at 1000dpi, 800dpi, 600dpi and 400dpi to see roughly where the failure stops. It may just be a 'memory' problem.
