 * Hi guys,
 * When doing a bit of site admin last night, I thought I’d see what this blue message
   on Foogallery plugin was all about, that just appeared in the last week, and 
   also appears on ‘FooBox’.
 * Found that I’d now got this message:
 *     ```
       Thumbnail Generation Alert!
       There is a problem generating thumbnails for your gallery. Please check that your hosting provider has the GD Image Library extension installed and enabled.
       If thumbnails cannot be generated, then full-sized, uncropped images will be used instead. This will result in slow page load times, and thumbnails that do not look correct.
       ```
   
 * …so I contacted my host and they confirmed that both ‘imagik’ and ‘GD’ were activated
   and running fine on other websites that were using these extensions.
 * So seeing as other websites have no problem with php image extensions, why does
   FooGallery keep nagging me (since the last update) that there is now a problem?
 * The page I need help with: _[[log in](https://login.wordpress.org/?redirect_to=https%3A%2F%2Fwordpress.org%2Fsupport%2Ftopic%2Fgallery-error-message%2F%3Foutput_format%3Dmd&locale=en_US)
   to see the link]_

 * Hi [@steveraven](https://wordpress.org/support/users/steveraven/),
 * Would you please go to FooGallery -> Settings -> Images and click the “Thumbnail
   Generation Test” button?
 * If that returns a “Thumbnail generation test ran successfully” response then 
   please go to FooGallery -> Settings -> Advanced and check the “Override Thumb
   Test” option and save.
 * Let us know if the warning goes away after that? Sometimes there are problems
   running the thumbnail generation test. This overrides the test to use a remote
   image from our CDN instead of directly from your website.

 * Hi [@phillcoxon](https://wordpress.org/support/users/phillcoxon/)
 * Yes that worked, though I had to follow your instructions in reverse order, as
   the thumbnail generation test gave another error.
 * After checking the ‘ovverride’ option though and running the generation test 
   again, all looks good.
