Larger thumbnails for attached pictures

[GlennLever]

Is there a way to make larger thumb nails for attached uploads, I would like them to be the same size as linked pictures.

If there is away please tell me where to update the option.

[Antechinus]

Admin, with the other attachment options. You can set it to whatever size you like.

I change the max wide and height to 1000, but still have small thumb nails

Seee the links below for examples

Hmm, it's hard to tell since it looks like guests can't see attachments.

However, if the thumbnail size is changed, all thumbnails should be resized as they are being viewed. On the one which won't resize, is the image smaller than the size you have set for thumbnails?

I reset the thumb nail size to 800X600

Thumb nail that is large is 592.62 KB 2048X1536

Thumb nail that is still small picture size is 68.31KB 800X533, when clicked on resizes to half screen size.


This one resizes


This one does not

If the image is smaller than the thumbnail size, a thumbnail will not be generated. However it looks like if there is a thumbnail, it still get's displayed.

If you delete that image and then reupload it. The thumbnail should disappear.

I am looking at the code and a quick fix might be possible. But I gotta do some checking first.

Ok, a proper fix for that. This will delete the thumbnail and update the database.

In Display.php look for:

Code Select Expand


if (!empty($attachment['id_thumb']))
$attachmentData[$i]['thumbnail'] = array(


And add before that:

Code Select Expand


// If the thumbnail size is increased and the image size is now smaller than that. Remove the old thumbnail so it don't show.
if (!empty($attachment['id_thumb']) && $attachment['width'] <= $modSettings['attachmentThumbWidth'] && $attachment['height'] <= $modSettings['attachmentThumbHeight'])
{
require_once($sourcedir . '/ManageAttachments.php');
removeAttachments(array('id_attach' => $attachment['id_thumb']), '', false, false);

$smcFunc['db_query']('', '
UPDATE {db_prefix}attachments
SET id_thumb = {int:id_thumb}
WHERE id_attach = {int:id_attach}',
array(
'id_thumb' => 0,
'id_attach' => $attachment['id_attach'],
)
);

$attachment['id_thumb'] = 0;
}
