ImageManager sometimes fails to display thumbnails

[koto@…]

ImageManager plugin does not display existing thumbnail files from images within subdirectories of $IMConfigimages_dir? if $IMConfigthumbnail_dir? is an empty string (i.e. if thumbnails are put in a same directory as image files). The <img> tag produced by plugin interface (rendered by images.php) refers to non-existing file, completely ignoring the subdirectories and assuming the thumbnail resides in $IMConfigimages_dir?.

E.g.: instead of referring to thumbnail automatically created during upload (http://example.com/images/subdir/second/t_image.jpg ) it refers to http://example.com/images/t_image.jpg

Such behaviour occurs only when $IMConfigthumbnail_dir? is an empty string.

Proposed (working) fix:

plugins\ImageManager\Classes\ImageManager.php

Line 315 (getThumbUrl() function) should read:

Return Files::makeFile($this->getImagesURL() . $path_parts['dirname'], $thumbnail);

instead of:

Return Files::makeFile($this->getImagesURL(), $thumbnail);

Hey, I had to the same problem, the fastest and the easier way to fix it is set change in file plugins/ImageManager/config.inc.php on the line numer 161 $IMConfigthumbnail_dir? = '.'; this fix to cause a thumnail directory is (become) the same directory as our image directory, this change take of the problem with unvisible thumbnails

Very likely this applies to EFM, too
