Squarespace developer tools template code photo resolution?

I have been a bad designer and now have a website with 12-years of large images...mostly product images that I loaded as /png files at 300 dpi, plus some other large files. 

I was talking with a friend the other day and he suggested there was a template I could use within the developer tools that would automatically resize all of the images loaded into my website. Has anyone heard of such magic?

Hello @afnbroadcaster, Unfortunately, there isn’t a magic tool within developer tools that can automatically resize all the images already uploaded to your website. You have options to clean up the image situation and improve your website’s performance without manually resizing every image.

• Desktop Tools: Adobe Photoshop, Affinity Photo, or GIMP for advanced editing.
• Batch Tools: TinyPNG, ImageOptim, or IrfanView. These can compress multiple images in one go.
