I went to add a test image and got the message:

File size error. : You tried to upload a image over 2mb

My server is configured for much larger uploads and I was able to add the same image in a blog post without any issues, so I’m assuming there is a limit set somewhere within GD.

Where can this be changed?

If it isn’t a setting in the admin UI, could it be added?

Cheers,

I have added a hook on that limit now, so u can easily add a filter in ur child theme functions.php, it will be available in next release.
After next release, plz add this code in your theme’s functions.php to change upload limit.

add_filter('geodir_default_image_upload_size_limit', 'geodir_change_default_image_upload_size_limit') ;
function geodir_change_default_image_upload_size_limit($limit)
{
   $limit = '10mb'; // change it as per ur need.
   return $limit;
}

Thanks

Cheers,
