Tettra allows resizing images using our size controls feature.
All images are centered aligned, and it's not possible to change this right now. To get some more customization, copy/paste is a great way to get images in to Tables, Team Home, Page Comments, and Answers to questions.
Click the image you want to resize to highlight it. After which, drag the size controls on the outside of the pink box until your image has the desired height and width.
