Bug discovered deletes category image

I discovered a bug in the use of category images that is fairly easy to recreate.

If two or more categories use the same image, editing any one of those categories to use a different image will cause the original image to be deleted even though it is still referenced by other categories.

Hi,

Thank you for this report. You can download the latest package from our website, it includes this hot fix.
Or you can directly edit the file "administrator/components/com_hikashop/classes/file.php" and in the function "storeFiles()" replace:

if((empty($keepFiles) || !in_array($old,$keepFiles)) && JFile::exists($uploadPath . $old))

if((empty($keepEntries) || !in_array($old,$keepEntries)) && JFile::exists($uploadPath . $old))
