This seems to be my day for QImage problems.

Scrolling through a directory that contains only tif files (mostly 48 bit and some 24 bit), QImage periodically comes up with an error: jpeg error #54.

The first time that happened, QImage closed. More recently, it carries on after I click the OK button.

This is version 2010.205 SE.

Tom,
I googled that error, and the replies are very vague to say the least.
What do you mean when you say you scrolled through a directory?  Are you referring to scrolling the thumbnails ?
Do you get the error if you change directories?
Can you rule out a corrupted image by creating a NEW FOLDER and transferring all the images back to teh original directory (jpgs only) a few at a time?

.... and by all means, please download and install the latest version of Qimage. That is imperative.

Fred,

Yes, the error occurs as I scroll through the thumbnails in one directory. It doesn't happen every time. There are no jpeg files, just tif files.

Selecting all, and then doing Preview/Add, I can step through all files with no problem.

So it is apparently a problem with thumbnail generation. I have the Studio Edition and a Core i7 that supports 8 threads at once and was using quad core thumbnail generation. So, thinking that perhaps it is some kind of timing issue while building thumbnails, I set it to use just one processor. But the error still occurs.

I never upgrade before starting work with QImage, or any other software. So that's why I was using 205. Now that I'm done with my project, I upgraded to 207 and the error still occurs.
