Does anyone know how I can remove the weird formatting of images from my blog? They seem to be zoomed in and slide around, meaning my carefully chosen photography is not working very well on my blog. You can see here: https://www.oxidatedesign.com/blog/the-3-shibori-masters-of-arimastu-japan Squarespace tech support told me it has something to do with the code in the header of my website. I paid someone to develop my site but they no longer do this kind of work, so I am a total novice and at a loss as to how to resolve. Any help is welcomed. 🙂
