SOIL Image size

Can I somehow get size of an image (of any SOIL supports)?

I know that there are different headers in image files which define these sizes. But is there any function from SOIL to get image size?

SOIL_load_image() will populate the width/height parameters with the dimensions of the image, though it does a full load of the image to do so:

/**
    Loads an image from disk into an array of unsigned chars.
    Note that *channels return the original channel count of the
    image.  If force_channels was other than SOIL_LOAD_AUTO,
    the resulting image has force_channels, but *channels may be
    different (if the original image had a different channel
    count).
    \return 0 if failed, otherwise returns 1
**/
unsigned char*
    SOIL_load_image
    (
        const char *filename,
        int *width, int *height, int *channels,
        int force_channels
    );

The underlying stb_image.h has routines that don't load the full image:

// get image dimensions & components without fully decoding
STBIDEF int      stbi_info_from_memory(stbi_uc const *buffer, int len, int *x, int *y, int *comp);
STBIDEF int      stbi_info_from_callbacks(stbi_io_callbacks const *clbk, void *user, int *x, int *y, int *comp);
STBIDEF int      stbi_is_16_bit_from_memory(stbi_uc const *buffer, int len);
STBIDEF int      stbi_is_16_bit_from_callbacks(stbi_io_callbacks const *clbk, void *user);
