JWST+HST NGC7496
Yes, you can use this image! The attribution line is:

As I work through trying out different ways to combine the data, this method stood out as particularly pretty, even if it lacks immediate scientific clarity. The glowing strands and flocks of dust, which would normally be dark in visible light imagery, are instead bright and glowing with infrared light from JWST.
A version showing just JWST data (dust) is here: flic.kr/p/2nyXMye
This galaxy in visible light from HST only is available here:
Data from the PHANGS-HST program were used to create this image.

Some processing notes and filter combinations:
JWST Filter Combination:
Cyan: [mathematical operation] NIRCam F335M-(NIRCam F300M+NIRCam F360W)
Orange: MIRI F770W
Luminosity (grayscale): MIRI F770W
JWST data are overlaid on HST data with a Photoshop screen layer mode.
HST Filter Combination:
Red: WFC3/UVIS F814W
Green: WFC3/UVIS F555W
Blue: WFC3/UVIS F438W+F336W+F275W
The upper right corner of the HST data was filled with cloned data to get rid of a hard edge where HST data were missing.
North is 83.25° counter-clockwise from up.
