... and two different images from the same EPS file are created. It  
is latex in DVI output mode that needs to know the bounding box:

	! LaTeX Error: Cannot determine size of graphic in Image.png (no  
BoundingBox).


I am beginning to understand now the actual details accompanied with  
DVI output format!

• PS and EPS files carry their BoundingBox. PNG, PDF, TIFF, GIF, SVG,  
and JPEG don't have exactly that, but their dimensions are recorded  
inside.

• Therefore LaTeX needs information on the bounding box for PNG, PDF,  
TIFF, GIF, SVG, and JPEG graphics files.

• Dvips can handle PS and EPS files.

• Dvipdfm can handle PNG, JPEG, PDF (just as pdfTeX does) and also PS  
and EPS, which are converted by external means into PDF.

Using a more complicated picture environment with cases for pdfTeX,  
latex, and TeX4ht will cure errors like that above.
