 * Hi team,
 * lately I’ve seen a warning message on my website:
    [http://www.spinips.com/settori/automazione-e-linee-produttive/](http://www.spinips.com/settori/automazione-e-linee-produttive/)
 * I think it concerns the image size and maybe it’s related to the automatic wordpress
   update. Can you help me someway? Thank you!!!
 * Laura

 * It looks like your image resizer plugin might not like using bitmap files. Switch
   to another format such as jpg, gif or png.
 * Also check your wp-config, making sure that define(‘WP_DEBUG’ is set to false:
   
   define(‘WP_DEBUG’, false);

 * Wp-config is ok, I tried disabling EWWW Image Optimizer plugin but nothing changed
   and I also checked for file format: I’ve got many BMP images, not just the ones
   giving problems…

 * Start by deactivating plugins. Let me know if it doesn’t go away.

 * The error is coming from ewww-image-optimizer but it’s because the function filesize
   failed.
 * It could be because of a corruption in a file you might just want to re upload…
 * Also It’s strongly suggested these days to not use BMP format and instead jpg
   or png for web.

 * Thank you all, I replaced the images with a jpg format and it worked!
 * Thanks again for your enduring support.
