Re: xcGallery - Making the Thumbnails look decent

Thank you so much! I deleted all the pictures and re-added them, and now it's fine! Bless you!!! Quote:

Actually, it is the thumbnails and the mid-sized ones that are affected. The full-sized ones are perfect (click on the mid-sized images). So the problem is in the reduction process. Why would I be having this problem while others are not? And choosing the GD2 instead of the default GD1 worked for the person above... I've tried all the options, including ImageMagick, but nothing changes...

It is not only the thumbnail, but also the other (normal) size is affected.
Weird assumption: It seems you have not enough memory to process all three basic colours.
Could you do the following test?
Take eg /modules/xcgal/displayimage.php?pid=14&fullsize=1 and reduce it with your photo editing program from 1600x1200 to 800x600 and 400x300. This would normally have not any visual impact and loss of the kind you are suffering now. Upload them and process them.
How do the thumbnails look?

Thank you for the reply, but the problem is still there. Yes, the jpeg quality is set at 100, the thumbnails are plenty big enough (I think they're at 200), and I've selected GD2. You can see my gallery at http://brunais.com/modules/xcgal/. See the problem I'm talking about? Quote:

Some kind of pictures let them easier compress then others. When there are no large objects or colour fields on the picture, you will end up with a grey square. See also to have a large range of contrast and good colour balance.
Did you set the quality of jpegs to 100?
Make the thumbnails also not too small eg 128.
Select GD2 for resizing.
And then it will look decent. But it will be a thumbnail after all and not a full fotograph.
