Image cropping for editors - best strategy?

[totoff]

Dear all,

tomorrow I'll have to introduce some editors on how to upload and edit images in image fields in Processwire. The site in question is quite image rich and I've spent some time to serve the appropriate images via scrcset already cropped for different screen sizes.

However, the backend offers a lot of possibilities to manipulate images and most of them I'm not familiar with because as a developer I've never spent much thinking on what all the features might be good for … Yet I'm concerned that my editors work on images in the backend may interfere with my optimization strategies in the templates.

Is there a general rule of thumb what content editors should do or not do with images in order not to break srcset strategies etc.? Maybe there is already a source of information you could point me to?

Your recommendations are much appreciated!

Not sure if this is what you're looking for (or if you already know about it) but explaining the focus feature to your editors might come handy for you when generating variations for srcset. If cropped, the image returned will respect the focus point and try to keep it centered.

@monollonom That's great, thanks for pointing me to this. Exactly what I was looking for.
