You can read many (older) image formats into a graphic field.
But Paradox will render into a BMP format on the form.
It can handle many formats, but some lose depth.

Reads a graphic from a file.

A Paradox table has a graphic type, again converts to BMP, but acts like
any other field.

I would not store MANY graphic files in a table, they are like Blob fields,
unwieldy. Better to store them in a folder and read them in on the fly.

The external viewer is most reliable, I use same thinking for PDFs.
