Quality of thumbnails.

[Kenneth K]

First of all thankyou for a great script. I have been looking for something like this for a long time.

I would like the thumbnails to be better quality, they are compressed too much. I have looked in the code for a parameter on the matter but couldn't find one. Can this be fixed and how?

Regards,
Kenneth

Open up admin/index.php and look for
imagejpeg($img, "../thumbnails/thumb_$file");

It's very close to the end of the entire script.

Edit that so it reads
imagejpeg($img, "../thumbnails/thumb_$file",100);

The 100 is an optional thing telling gd to use as little compression as possible.

Great that was it! Thx for the quick response. Now the thumbnails are nice and clean but not very sharp. I've checked the latest gd documentation (2.0.28) and I see that gd has a sharpening function (gdImageSharpen) is it possible to add that fuction to the thumbnails so they could be sharpened?

Try to add it and see what happens.

$img = gdImageSharpen($img);
Just above the line you edited for compression.

Test it, tell me if it works!

Well, I have no idea how and where to add it but I gave it a try and got this error:

Fatal error: Call to undefined function: gdimagesharpen() in /var/www/hotels/.dk/pinx/html/photoblog/admin/index.php on line 842

Edit: Wait I was a bit quick there. I get this: Fatal error: Call to undefined function: gdimagesharpen() in /var/www/hotels/.dk/pinx/html/photoblog/admin/index.php on line 837

when I try to resize thumbnails.

My guess would be that your gd-version don't support that function (gdImageSharpen).

That is what the error says.

I've checked and my host runs gd 2.0.28 and gdImageSharpen was added in ver. 2.0.16 so I don't think that's the problem.

Oh darn. It's not yet implemented in PHP unfortunately, that was the problem.

Ah ok. It would be cool if it worked.
