Why are there no better photos of Venus?
Short answer: It's too hard.
Long answer: Venus and Mars are the two closest planets to Earth. We have thousands of incredible photos of Mars but when you search for photos of Venus the results aren't so impressive. Why is that?
Venus is a surprisingly difficult planet to photograph. For starters the entire planet is permanently covered in thick cloud so you can never see the surface from space (at least not in the visible light spectrum). Any photos of the planet will be fairly featureless like this:
If you see a photo of the planet Venus that shows details, you're looking at at different type of image such as a radar image.
The only way to get visible-light photos of the surface of Venus is to land a spacecraft on the surface. This is very challenging because the environment is extremely hostile. The only landers that have ever made it to the surface have lasted less than a few hours before dying. The last attempts to do this were in the 1980s when digital camera technology was primitive. This, along with the terribly harsh environment, means that we only have a handful of low-quality photos taken from the surface of Venus, like the one below.
