Hello. Thank you for contacting the Toolset support.
I would like to have little more clarification here.
Do you want to display the image in defined height and width or you mean when you used the code you shared is just do not display the image? Can you please clarify this first.
In addition to that, Can you please share problem URL where you added the code you shared as well as access details.
*** Please make a FULL BACKUP of your database and website.***
I would also eventually need to request temporary access (WP-Admin and FTP) to your site. Preferably to a test site where the problem has been replicated if possible in order to be of better help and check if some configurations might need to be changed.
I have set the next reply to private which means only you and I have access to it.
we want to use the famous "WP Offload Media Lite for Amazon S3" plugin in order to upload our images to Amazon S3. The plugin is working correctly and upload the images to S3 except for the thumbnails where created from the Toolset View and have the extension -"wpv_150x130.jpg and -wpv_300x200.jpg ". These images we suspect that are created from the code below
When a user creates a new post with an image attached, the -wpv_300x200.jpg has not been created yet, but when a user goes to the list view where that above code exists then is created and is not uploaded to S3 folder.
Custom sizes you use with the shortcode is not compatible with the plugin you are using/
If you want to use the Custom image size, you must register that image size first to your theme's functions.php file or you must only use registered sizes.
If you still find it doesn't work how they expect when using registered sizes then you may have to use the plugin option which keeps a copy of the images on the local server as well as offloading them, I'm not sure yet if that option available with lite version or that option only available with the Pro version of your plugin.
In addition to that disabling keeping a local copy may produce compatibility problems with other plugins.
Can you please check above steps and let me know how it goes, otherwise it will require further investigation.
