Hi

How are You?

I have a problem with the accesbillity: I made a test on https://wave.webaim.org/
and in the footer is a small green house icone

The https://wave.webaim.org/ test says there is not a alternative TXT
but I put it into the code:

CHRONIMY PLANETĘ

and I addes the alternative TXT on this image in my WP Gallery
- still nothing :(

What can I do to fix it ?

Thx
Robert
