you could use evas_object_image_load_size_set as well. But I have no
idea what this function do exactly, I just experienced load speed up
when I specify the size of the container. I guess it's only usefull
for jpeg images (maybe svg ?)

you should maybe use elm_photocam_zoom_mode_set(im,
ELM_PHOTOCAM_ZOOM_MODE_AUTO_FIT) ?

It's what I was talking about :P
