Error after Upgrading; Error: Premature end of script headers

[macblue]

I've upgraded from the version 1.3.1 to 1.4.3
and now I'm getting an Internal Server Error 500 with some pictures (mostly all pictures in an album)
In the error log of my web space provider it's written

Premature end of script headers: /***/public_html/gallery/displayimage.php

and immediately after that

File does not exist: /***/public_html/gallery/500.shtml

I've download the whole cpg 1.4.3 package from a different ftp server then before and unloaded it again (except: config.php)

all files passed the versioncheck.php up to 1.4.3

So I created a new album called "test pictures" with 2 pictures that were displayed correctly and 2 that weren't
1. downloaded them
2. renamed
3. uploaded
4. batch added into the album "test pictures"
5. added titles to the pictures (with the AdminTool)

the 2 pictures that worked before still do, but the other 2 still don't
then strange I got to see a strange phenomenon
BUT if you start a slideshow from one of 2 pictures that is displayed, it will show all pictures correctly

here the link
http://gallery.macblue.net/thumbnails.php?album=52

I'd like to get my gallery functioning again, soon.

Does anyone have a clue?

yes: the pics that don't work are too large for your webserver setup.

Try disabling the reading of EXIF data in config, it can cause issues with invalid or unusual EXIF data.

Thanks for the tip.

With the help of my webspace provider I managed it.
They commented in the file /include/exif.php the line 633 out.
Now it works well.

but without EXIF data
:-\

commeting the include out wouldn't have been necessary, as there is a config option for this
