Hi!
I'm having problems with myalbum-p's thumbnails - they seem a bit off in the colors, a bit desaturated. Have anyone else experienced this?

In the MyAlbum-P Module Preferences switch Package Treating Images (3rd option down) to NetPBM. You will then have to Rebuild Thumbnails using the menu in the Modules pulldown.

Let us know how it goes.

hmmm.. I'm not sure I can install anyone of those on the final webserver.. Is it GD2 that makes the images so crappy looking?

Strange.. Somehow I cannot edit the original post!?

Anyway.. I found out that I can use ImageMagick on the server, but I'm still wondering.. are the images supposed to look like this when they're converted using GD2? The colors are totally off:

Found the problem...
I was reading the GD library faq, and it seems that Myalbum has a little bug:

Quote:

Why do my JPEG thumbnails have missing colors with gd 2.0.x?
When creating truecolor images, you need to call gdImageCreateTrueColor, not gdImageCreate. This used to "work" in gd 1.x, but only in the sense that gd 1.x had no support for real truecolor at all, so it faked it by dithering your image. gd 2.x supports real truecolor, and also has a better way of reducing to palette color when you really want to do that; see the gdImageTrueColorToPalette function -- but you don't need it for this job. PHP and Perl programmers: the function names for you are similar, just leave off the gd prefix.

So chainging line 134 in myalbum\admin\functions.php to this will handle the problem:

 //$dst_img = imagecreate( $new_w , $new_h ) ; 
$dst_img = imagecreatetruecolor( $new_w , $new_h ) ;
