This article was previously published under Q197321 SYMPTOMS
Microsoft Internet Explorer 5.0 and other image programs allow you to
successfully view .jpg files that were created using a Sony Digital Camera
However, you may receive the following errors if you attempt to use the
file in Visual Basic:
Run-time Error 321, Invalid File Format; Unable to display image when
using ImgEdit OCX provided within the Wang Imaging Controls suite with
Windows 95 or Windows NT 4.0.
-or-
Run-time Error 75, Path/File Access Error; Unable to read or write the
specified file; Unable to display image within the Kodak Imaging
Controls suite with Windows 98 or Windows Me.
CAUSE
The following paragraph is from the Eastman Software Web page:
The Sony Mavica Digital Camera generates .jpg files without the required
"JFIF" string in the header. The JPEG standard states that an APP0
marker and "JFIF" string, together with the leading SOI marker, make up
the header that identifies them as "standard" JPEG/JFIF files. Some
applications just recognize the leading "FFD8" SOI marker and do not
look for the "JFIF" stamp, thus allowing them to open a wider variety of
JPEG files. The Wang Imaging Controls follow the specification, so if
the JFIF string is missing, the current versions of Imaging raise an
invalid file format error. This error is generated in both Imaging
Professional as well as Imaging for Windows. Imaging Professional 2.0
does the more lax "FFD8" check, and so is able to read the Sony Mavica
files.
RESOLUTION
Currently, the only workaround is to purchase Imaging Professional 2.0.
