Blog Featured Image


Newbie here - please be nice and not too technical.

Our website has been running for a while but I get increasingly frustrated with the blog featured image.

A: I want it true colours and not greyed.
B: I want no writing as I would like to place writing on the original picture.

For example, I do not want the white writing and this picture originally is really vibrant colours.

Where is the setting to do both of these things? I have gone through the jupter theme settings 100 times.

Thank you in advance for your help.
