Re: Only Png Mid Thumbnails Cached, No Jpg Thumbnails
-----------------------------------
I fixed this.

file album_picm.php line 423

Changed this line from

[code linenumbers=false]			$Image->SendToFile($pic_thumbnail_new_fullpath, $album_config['thumbnail_quality']);[/code]

to

[code linenumbers=false]			if ($pic_filetype == '.jpg')
			{
				$Image->SendToFileJPG($pic_thumbnail_new_fullpath, $album_config['thumbnail_quality']);			}
			else
			{
				$Image->SendToFile($pic_thumbnail_new_fullpath, $album_config['thumbnail_quality']);	
			}[/code]
