/**
* Create thumbnails and update the corresponding Product records
*
* Scans the Products with the given IDs. If a non-empty picture string
* with a reasonable extension is encountered, determines whether
* the corresponding thumbnail is available and up to date or not.
* If not, tries to load the file and to create a thumbnail.
* If it succeeds, it also updates the picture field with the base64
* encoded entry containing the image width and height.
* Note that only single file names are supported!
* Also note that this method returns a string with information about
* problems that were encountered.
* It skips records which contain no or invalid image
* names, thumbnails that cannot be created, and records which refuse
* to be updated!
* The reasoning behind this is that this method is currently only called
* from within some {@link _import()} methods. The focus lies on importing
* Products; whether or not thumbnails can be created is secondary, as the
* process can be repeated if there is a problem.
* @param integer $arrId The array of Product IDs
* @return boolean True on success, false on any error
