TYPO3 Core

And for other file types (e.g. gif, pdf, etc.) this is working?
One thing I've seen often is a wrong path setting:
Switch to your Install Tool, goto All Configuration and check if the value entered at 'im_path' is correct

In my backend there are thumbs generated for "*.jpg" but not for "*.JPG". I thought this is case insensitive. I use T3 Version 4.0.2

the same here
threre are not thumbnails for images with upper ".JPG"

For the upper-/lowcase crowd:
Could you please point out <b>where</b> these files are not displayed? While editing a record, in fileadmin/filelist view, in element browser... Thanks in advance!

There was a similar issue in the element browser, which is fixed in TYPO3 4.1.3 - see bug #14146

yes it was the element browser in version 4.1.2.
So i've have to update this site...
thx

same for me. I have updated. Thank you.

@Ohk: Could you please mention, when the error occurred on your system? Did you update a running system with a newer TYPO3 release? Or did you just set up a new TYPO3 project and had this error? Maybe the typo3temp directory hasn't the required permissions - the result would be that thumbnail files couldn't be written at all.

Hi !

We have a similar problem here ... here for images which have a "space" character in their name no images get generated - I assume that somewhere in the t3lib_stdGraphic code where images get resized by imageMagick there are no quotes (") around image filenames - which would cause problem if the contain a space-character.

Could you test renaming files which cause problem to such a name where they do not contain any spaces ...

Resolved, no change required:

The issue with the uppercase filenames has been solved in 4.1 and 4.2 with revision 2513 / 2514, see #14146

I was unable to reproduce the problem regarding space characters in filenames. This might have to do with my gfx environment, so I can not be 100% sure if this is really solved. @Bernhard: Could you please open a new issue if this is still a problem for you?
