It happens after I confirm the images.

I’m using a theme from Elegant Themes. It has several different thumbnail sizes defined. However, some are the same size. For example, pageimage, blogcat, and singleblog are all 200×200. I suppose this would allow a person to modify the sizes individually when modifying the theme.

There are two scenarios:
1. More than one thumbnail in the selected set has the same size.
2. Each thumbnail in the selected set has a different size.

Scenario 1 will cause the problem. In addition, the other thumbnails in the selected set with the same aspect ratio but different sizes may not be updated.

Scenario 2 will work properly. The result is that all the same sized thumbnails are updated and any additional thumbnails are also updated.

As for what ends up in the ptetmp directory, I’ll have to give that another try and have a look. It’s a bit late now so that will be tomorrow morning.

I found that if I edit a batch of thumbs but there are more than one with the same exact dimensions, I get the blank screen and some of the thumbs don’t get created. While I haven’t looked too deeply into this, I believe that only one copy of the duplicate thumbs actually exists and something is going wrong when a second one is edited. This can be seen by editing one of them (in my case a 200×200 pixel thumb) and noticing that all the same sized thumbs change.

I hope this helps.

This appears to happen if you try to set two thumbnails that have the exact same dimensions. I have several thumbnails that are 200×200 pixels but have different names. If I edit one of them, they all change but if I edit more than one, I get the blank screen.

I hope this helps.
