General Support: A few albums lacks source URL for thumbs in the actual PHP code

Hello again.

Still going strong with Plogger Beta3. Still not migrated to RC1.

Anyway I have arond 11.500 thumbs and photos generated in Plogger (thumbs and intermediary files) along with the original photos.

Divided in 5 collections with anywhere from 10 to 88 albums in each collection.

A problem has arisen.

In one of the collections, the one with 88 albums, the thumbs (both the album thumb itself and the album's thumbs diplasyed for each photo) are missing as well as the intermediary photo. All other collections have 100% functioning albums.

The mysterious part is that the souce code shows that the src-URL tag for each missing thumb/intermediary photo is blank. In other words, the actual page does not show the thumbs / intermediary phots, because the code does not contain the source URL for any file.

I will show you:

1.Working thumb
<li class="thumbnail"><div class="tag"><a href="/bilder/?level=album&amp;id=148"><img class="photos" src="http://www.domain.com/plogger/thumbs/4038-img_3554.JPG" title="" alt="" /></a> <br /><input type="checkbox" name="checked[]" value="148" /> 86 Juleklar <br /><div class="meta-header">(48 billeder)</div></div></li>

2. One of the dysfunctional /broken thumbs
<li class="thumbnail"><div class="tag"><a href="/bilder/?level=album&amp;id=147"><img class="photos" src="" title="" alt="" /></a> <br /><input type="checkbox" name="checked[]" value="147" /> 85 Føs'da 2 <br /><div class="meta-header">(22 billeder)</div></div></li>

Only the source URL tag is blank - the rest of the code is working perfectly for this album/thumb.

The two code bits are chosen from to adjacent albums/thumbs, where one is working and one is not. Only the mentioned URL in the wokring code has been modified. All other was left as copy/pasted from the page source.

It was not always like this, of course, with the broken/missing thumbs. The broken albums were created a year ago and were working fine originally.

I have upgraded Plogger to beta3 a long time ago, and I have cleared the thumbs folder once, recently.

Anyone with ideas on what is wrong/causing this AND how I can fix it?

Thanks. A lot!
