Fuzzy thumbnails

StJoris / 2009-08-27 16:00:36   

Hey all,

I've been trying to get my thumbnails to be bigger in thickbox by using the method described in other parts of the forums:

Changing the $lowest value to a fixed one, say 200, in the exhibit.thickbox.php

I tried increasing the thumbnail upload size to 300 and 500 and re-uploading everything, but it still stays blurry.

Any clues?

Thanks

The reason this doesn't work is because this format finds the smallest height of all the thumbnails and then uses it. If you manually set this value it does not mean the thumbnails will necessarily be big enough (because of the cropping).

When I view a thumbnail directly it's height is still less than 200...hence the bluriness.

Ah yes thank you, that helps somewhat, I think that means that something is wrong then with supplying the bigger thumbnail images.

I did this in the default.php

$default['thumbsize'] = array(100 =>100, 150 => 150, 300 => 300, 500 => 500);

is that the right way to get to use bigger thumbnails?

Yes, but will it be 'big' enough after resizing?

Maybe.

Hah I found out what was the culprit.

The images are very landscapy, long images. So when the thumbnail button was set to 500 and a picture uploaded, it makes the 'long edge' 500 px. On the other hand, the thickbox takes the 'short edge', which was set to 200px.
But because of the so oblong proportions, 500px long edge resulted in a

Yup, that's what I was getting at.

I found myself in the same situation-- longer-width images are appearing very blurry as thumbmnails in thickbox after I had edited line 48 of exhibit.thickbox.php to read:

  1. $lowest = 150;

Is there a way to get rid of the blurriness on these wider thumbs? I couldn't glean that answer from above. Thanks!

Try making the Thumbs size bigger...but then you have to reupload the images to get new thumbnails.

Excellent-- that worked, thanks Vaska!

Excellent. Exactly what I was also looking for also.

Incase this is of use to anyone else..

I wanted to get larger thumbnails for a thickbox exhibit as i Had some wide images this was causing thumbnails to be very small and/or blurry.

To fix this, i edited the defaults.php file and change the thumbs sizes to:

$default['thumbsize'] = array('normal' =>300, 'wide image' => 500);

When up loading wide images the "wide image" option is selected.

Then I edited the thumbnail height in the exhibit.thickbox.php file, bypassing the smallest height function.

I understand how to get more thumbnail sizes in default.php but can anyone elaborate on what I need to do in thickbox.php? Still can't fix the blurry-ness.

Show us your site...

here's an example of the wide thumbnail squishing the others:

So I'd like to make them all bigger, which I can do using the defaults.php but then I get the pixelation.

I cleaned my links, so now the example is at: http://hmillerdesign.com/projects/emi-music--bill-charlap/

Can anyone help me rid my site of these tiny thumbnails?
