Thumbs have minor artifacts...

Hey guys, I'm using a script from a book to do auto-thumbnail creation and it works great on my server. However I am a little dissapointed that the quality of the thumbnails is not very high as I can see some grey artifacting around the main images (in the whitespace around logos, etc). What can I do to turn up the quality setting for thumbnailing? I am afraid I can't post the code from the book because I don't want to do anything against the copyright stuff. Thanks!

Sounds like it was written for an older version of GD. Change imagecopyresized() to imagecopyresampled()

Otherwise, I think we'll need to see the code.

Hey feyd,

I just checked the code and it uses the imagecopyresampled() function. I think I fixed it, as I am testing it now and so far everything looks better. I found the imagejpeg() function and added the "quality" (1-100) rating as the third parameter and it looks a lot better. I think it was defaulting to the default quality 75. Thanks for the help!
