Blurry image (featured item on homepage)


First of all, english is not my native language, sorry for my syntax :s.

I try to put an image on my homepage using the featured item option.

It works great, except that the image is blurry (

Is there a way to solve this ?

Thanks in advance for your help.

It looks like your square thumbnail constraint is set to 200, so those thumbnails are generated as 200x200 pixel images. The space you're showing it in on the homepage is a little over 300x300, so the browser has to blow up the image to make it fit, and that's what makes it blurry.

You can increase that constraint in your Appearance settings on the admin side. To make the new, larger constraint apply to an existing image, you'll either have to re-upload the file, or use the Derivative Images plugin to regenerate the thumbnails.

I installed Derivative Images but when i try to regenerate the thumbnails, i get this error:

I get the same error when i try to reindex records (in "settings", "search").

ps : sorry i put my omeka in french so i try to translate the best i can.

Omeka tries to guess the server path to PHP for running from the command line. It looks like it's guess /usr/bin/php is wrong.

Check with your server admin or hosting company what the correct path to PHP's command line interface is. Then, in application/config/config.ini look for this line:

background.php.path = ""

and add that path as the value
