MBS XLLIB plugin invalid jpg file (in Excel file)

I try to read a excel file using the MBS XLlib plugin. In a file of an Spanish bank there is a jpg logo in the excel file.

The XLBookMBS is giving an error on load: invalid jpg file

In Excel I can open the excel file without any problems. I am not interested in in the jpg file, but only in the data in the Excel file. Is there a way to ignore this error so I van process the data in the Excel file without manualy first have to remove the jpg file?

Well, you could of course email us (or LibXL support) the Excel file to check.
Otherwise I can check if we could ignore the error.
