| Summary:

JWST has revolutionized the field of extragalactic astronomy with its
sensitive and high-resolution infrared view of the distant universe. Adding to
the new legacy of JWST observations, we present the first NIRCam imaging data
release from the JWST Advanced Deep Extragalactic Survey (JADES) providing 9
filters of infrared imaging of $sim$25 arcmin$^2$ covering the Hubble Ultra
Deep Field and portions of Great Observatories Origins Deep Survey (GOODS)
South. Utilizing 87 on-sky dual-filter hours of exposure time, these images
reveal the deepest ever near-infrared view of this iconic field. We supply
carefully constructed 9-band mosaics of the JADES bands, as well as matching
reductions of 5 additional bands from the JWST Extragalactic Medium-band Survey
(JEMS). Combining with existing HST imaging, we provide 23-band space-based
photometric catalogs and photometric redshifts for $approx47,500$ sources. To
promote broad engagement with the JADES survey, we have created an interactive
{tt FitsMap} website to provide an interface for professional researchers and
the public to experience these JWST datasets. Combined with the first JADES
NIRSpec data release, these public JADES imaging and spectroscopic datasets
provide a new foundation for discoveries of the infrared universe by the
worldwide scientific community.
