CellPad 0, CellSpace 0, Border 0, can image be 100% of width?
If the table/cell is....
CellPad 0, CellSpace 0, Border 0, 150 px wide...
Then it's ok to insert an image that is 150 px wide, right?
I mean, since the attributes are all 0, the image can be the full width of the table/cell without stretching it, or screwing anything up, right?
Or should I make the image a couple pixels less wide to be safe?
No you are correct. 150px wide image will fit EXACTLY into the width table you describe.
