Preview images broken after Upgrade - [Seems to be solved]

[dirkzc]

Hi, yesterday I switched my website to Joomla 4 and upgraded jDownloads as well. It seems to work, except there are a couple of preview pictures missing now. The downloads however are correct.
Is there a way to regenerate the preview icons automatically?

Regards,
Dirk

Hi
The basic answer is Yes.
Please see
https://www.jdownloads.net/documentation/options-configuration-v3-9/pictures-and-buttons-options#image-thumbnail-settings
You first need to ensure that the GD Library is present as explained in the article.

Hello Colin, thanks for your reply.
As I just found out, it is not just the automatic generation of preview images that is broken.
It also is no longer possible to assign new preview pictures to the downloads.
Very strange.

Hi
I have no problem with creating preview images.
Can you positively confirm that that GD library is present by looking at jD Options - Pictures and Buttons tab
It is quite a long way down in the Thumbnail Settings from Uploaded Images.

Yes, here's a screenshot of my settings:

Hmm!  Think I will need to look at your site in more detail.

Will send you a Private Message, PM, as they are secure.
Best wishes
