First, sorry if this has been already posted, but I only found this thread.

I have been testing the following to use jpegs as thumbnails for GIF images. I have used function imagecreatefromgif (which it seems to me it may work with all PHP/GD versions as it is a read-only function) to read the GIF and then, send the image to the browser as jpeg.

It works for me with automatic thumbnails and generates the cached image as jpeg.

Code: Alles auswählen

#
# ---[ OPEN ]----------------
#
album_thumbnail.php

#
# ---[ FIND ]----------------
#
if( ($pic_filetype != '.jpg') and ($pic_filetype != '.png') )

#
# ---[ REPLACE WITH ]----------------
#
if( ($pic_filetype != '.jpg') and ($pic_filetype != '.png') and ($pic_filetype != '.gif') )

#
# ---[ FIND ]----------------
#
case '.jpg':
	header('Content-type: image/jpeg');
	break;

#
# ---[ BEFORE ADD ]----------------
#
case '.gif':

#
# ---[ FIND ]----------------
#
case '.jpg':
	$read_function = 'imagecreatefromjpeg';
	break;

#
# ---[ BEFORE ADD ]----------------
#
case '.gif':
	$read_function = 'imagecreatefromgif';
	$pic_filetype = '.jpg';
	break;

#
# ---[ SAVE ]----------------
#

Can anyone confirm if this is a valid approach? ...or am I lucky with my hosting?

Thanks
