Negative text filters – list results not matching a given query.
- Use -.png or -.gif or -.jpg as filter in the network panel.
- Many other negative filters work too. e.g. -mime-type:image/png, -larger-than:20k, -domain:yoursite.com, -status-code:404. See Chrome developer docs – filtering.
Available since Chrome ~42 – Issue Link, announced here
Another approach: In the Network panel open the filter and CTRL/CMD-click the types of requests you want to show. To hide just image requests then select all the other types except images while holding CTRL/CMD.
