[TYPO3-english] PNG with alpha and (small) thumbnails in BE

[Jogvan Olsen]

Hi

I use some PNG files with alpha channel (PNG24 created in Photoshop) - 
but I can't see any thumbnails of the PNG24 files in BE. Thumbnails form 
JPG file works fine.


The strange thing is when I select Media>List and select 'Thumbnails' 
from the dropdown menu in the top of the screen - I can see 'big' 
thumbnails of all files (png24 and jpg). But when I select 'List' from 
the dropdown menu, and choose Option>'Display thumbnails', I only see 
thumbnails of my JPG files - thumbnails of png24 files are clear/invisibly.

Can anyone tell me what I am missing?

thanks in advance
Jogvan Olsen


I use:
TYPO3 ver. 4.2.6
DAM ver. 1.1.1
FireFox 3.0.10


In my localconf.php I have:
$TYPO3_CONF_VARS["GFX"]["gdlib_png"] = '1';
$TYPO3_CONF_VARS["GFX"]["gdlib_2"] = '1';
$TYPO3_CONF_VARS["GFX"]["im_imvMaskState"] = '1';
$TYPO3_CONF_VARS["GFX"]["im_version_5"] = 'gm';
$TYPO3_CONF_VARS["GFX"]["TTFdpi"] = '96';
$TYPO3_CONF_VARS['GFX']["im_path_lzw"] = '/usr/bin/';
$TYPO3_CONF_VARS['GFX']["im_path"] = '/usr/bin/';
$TYPO3_CONF_VARS['GFX']['jpg_quality'] = 100;
$TYPO3_CONF_VARS['GFX']['png_truecolor'] = 1;
$TYPO3_CONF_VARS['GFX']['thumbnails_png'] = 1;
