Image path does not update when setting a new crop.

Oh no. I've just realised that I got that wrong. Without Contextual Crop, I have an additional query parameter that updates when a crop is made. This does not exist on contextual cropped images.

I'm not very experienced with backend programming, so this is a bit difficult for me to figure out.

That's a main issue

Can you be more precise with the site configuration (modules involved, configuration on image styles....), URL generated, some screen-shots...

Thanks

I have written a patch that solves my problem. But I am not completely sure if it is the correct approach.

I'll try to summarise the problem again:

For non-context-based crops, the URLs to the image styles have an additional query paramter ‘h’. This updates itself based on the crop and serves as a cache breaker for browsers/CDNs because the actual URL does not change.
