JPG images store additional picture information in the EXIF header of each file. ThumbHTML will extract a selection of the most useful data elements if available (editing and saving JPG files often destroys this information).
Whenever you browse to a new folder containing images, ThumbHTML will generate a file containing the EXIF data with these images and save it to that folder as exifdata.txt [example].
The format of this data file, in which each field is delimited by the | symbol, is suitable for import to a database or Excel.
If the EXIF data are not available, the program uses the existing date and time, and filesize, of the file.
All this information, together with the picture comments entered by the user, can be exported to a file 'pictureinfo.txt' by using the appropriate menu item.
If you check the menu item "Display EXIF data with thumbnails" on the Tools menu, ThumbHTML will display the EXIF data as you browse through the set of images, giving a display like that shown on the right
Exporting EXIF data to Excel
From the menu, it is possible to export the EXIF data to an Excel spreadsheet. The file is saved to the root folder using the filename exifdata.xls.
