Info on sizing and placing of Images in ZOHO Writer as part

Hi I am just getting familiar with you exciting product.
Initially, I will be posting various articles etc. to a WordPress.Com Blog.
I was seeing how things work and uploaded a picture into Writer. It showed up very large. I have tried reading and looking around on ZOHO but can't figure how to size and position an image.
Do I have to set size dimensions in some other editor first?

Thank you in advance.
