Does 320x100 replace 320x50?

No. Many slots are hard-coded to 50 pixels of height and will not serve the taller creative at all. Produce both, since the second layout derives directly from the first.

Is 100 pixels enough for a product photo?

Enough for a cut-out product, not for a scene. Use the image as a square block on the left edge so the right side keeps one continuous area for copy and the button.

Which file format and file size?

myfeedr delivers 320×100 as PNG (lossless) and JPG. For trafficking, the JPG is what counts: around 35 KB is a realistic target for this size – small enough for any network without visible quality loss.

What does the format cost?
