What's wrong with image dimensions?

Yes, what's wrong? I say you - pretty much is wrong. I've completed a kind of little study for our firm about how well is image optimization in times of mobile first. You know what! I was disgusted twice:

1. roughly 85% images are oversized - this is not a dark secret, we are used to this in the meanwhile,
2. roughly 20% images are oversized in terms of dimensions: it means 20% of original images are higher than their displaying dimensions.

Screaming Frog 9.0 renders websites with Chrome 60

The new but not obvious thing in Screaming Frog 9.0 is the rendering engine. You should know - it isn't Chrome 41 (41.0.2272.118), which is used by Google's web rendering service (WRS). With it Screaming Frog can't render websites to 100% as Googlebot. But approximately identically to ;)

It is rather Chrome 60 (60.0.3112.113). This Chrome version was choosen by Screaming Frog developers as more stable AND with fewest rendering differences to the Chrome 41. You can compare both versions more detailedly at https://caniuse.com/#compare=chrome+41,chrome+60.

According to Screaming Frog support Chrome 60 version was selected due to working stability with the spider engine at scale, rather than because of rendering issues.

You can see the current Chrome version in the debug window:

How to disable Excel preview in Windows Explorer on Windows 7 and Windows 10.

Preview of Excel tables, specially of bigger size, can go pretty hard on the system performance. Some ressources recommend to use setting of Windows Explorer - but on this way one can only disable ALL previews.

With any file extention there is a Preview Handler associated. To disable only Excel previews, but to keep all other, which aren't so performance hungry, like previews of images or PDFs, one should edit (better as delete) one key in Windows registry.

• Start registry editor with regedit: Start → Run → regedit
• Find under HKEY_CLASSES_ROOT\.xlsx\ShellEx\ the key called {8895b1c6-b41f-4c1c-a562-0d564250836f}
• Edit it (i don't recommend to delete it), like on screenshot:

• Close regedit,
• Restart Windows Explorer: (Start → Run → Type cmd →Enter → Type taskkill /f /im explorer.exe → Enter → Type explorer.exe → Enter)
• Enjoy (tested on Windows7 and Windows10)
