Hello @JackM581. Thanks for coming into the Community! I looked into your account and saw that you are using our third-generation editor to create your emails. We have some great articles from our Knowledge Base that provides more information on how to insert and align your images:
I can understand how important it is to easily create your email campaigns! I apologize you are unable to see the image resizing tools. What browser are you working in? Is this still happening when you try through a different browser or a private/incognito window? With that said I was unable to replicate this same experience. In fact I was able to see these resizing arrows in your most recent email draft.
I was trying to resize two images in an Event landing page. They don't work the same way as in designing an email. No problems so far with the emails but the Event landing page wasn't working the way I was hoping it would.
