URL manipulated images not updating when original file changes

[enzomglb]

Hello, it seems that URL manipulated images don't get updated when we make changes to the original file. Eg:

I call imagecache/135x135/images/test.jpg and I get a nice 135x135 thumbnail from my custom template.

But if I modify the original image...
Image::make('images/test.jpg')->greyscale()->save();

... and the hit again imagecache/135x135/images/test.jpg I'm going to get the exact same thumbnail as the beginning since it's going to load the cached version of the thumbnail, ignoring the changes on the original image.

Maybe it shouldn't load the cached version when its modification time is older than the original's file one.

Thanks for your time and effort with this package!

At the Moment this is normal behaviour. Cache must be cleared no keep up with changed originals.

Comparing the modification times Sounds like an interesting idea. Maybe there is a fast way to do that.

That'd be great, I don't think it could affect performance that much running something like filemtime()...
In the meantime, What do you suggest as a temporary solution? I can't see how I can handle cleaning the cache for that particular file since the URL Manipulation function only lets us define templates... Any idea?

[olivervogel]

I'm afraid there is no quick solution. Intervention Image uses illuminate/cache to store cached images. And as far as I know there is no way to get the age of any particular data in cache, which might be configured to store data not only in filesystem but also Memcached, Redis or any other implementation.

The old cached image file will live forever in the filesystem? It seems that way. Shouldn't it remove the old ones when the new is generated?
