JPEG vs. Bitmap
In order to customize our reports for each customer, I'm loading their logos
into TppImage components before running reports. When WebTier runs reports,
it scales them, converts them to JPEG's, and saves them in report\images.
When I'm loading these images (TppImage.Picture.LoadFromFile), would it be
better for quality and/or speed to load bitmaps or JPEG's? If I loaded them
as JPEG's, would this allow WebTier to skip the conversion from BMP to JPEG,
or would they be converted to BMP and back to JPEG anyway?

The Page object sent from the server to the webtier will be smaller, if you
use smaller sized images. The server is compressing the page objects so I am
not sure how much it matters. The WebTier will convert the image to a bitmap
prior to saving it as JPEG or GIF.
