The easiest way to transfer images is to use TealPaint's 'Import from JPEG/GIF/BMP' and 'Export to JPEG/GIF/BMP' menus to transfer files to/from an external storage card or internal card volume.
Without a card, you can use the 'TealPoint Image Manager' under Windows to view, import, export, and print images in TealPaint format databases. There is also a DOS version under that allows you to do the same operations from a batch file.
These utilities work on PDB files backed up onto your PC when you HotSync. First check to make sure the database is marked for backup in the image database 'Details' screen, then HotSync to transfer the image to the desktop.
