> My image cache size grows really quick when browsing some images from

> 
>         emacs -Q
>         M-: (clear-image-cache)
>         Then, I open a image in a directory with other images.
>         I hit 'n' 5 times (to open next 5 images).
>         Each image is a JPG of about 1.3MiB.
>         Then, M-x memory-report says:
>            366 MiB  Total Image Cache Size
> 
> With such growth, Emacs quickly tells me that the memory is exhausted.

Did you try to lower the value of image-cache-eviction-delay?
