Image styles not working with preset image

I have been all the morning searching for info about how to use styles with the preset image of ImageCache Profiles but I haven't found anything clear yet.

The field on the ICP settings only allows you to put a path+file name so if you display several sizes on your profile (using for example the Heartbeat activity blocks), all the images will have the same size.

I thought that uploading the Avatar using Avatar Selection module (this automatically create the different styles that you have set up) I will give ICP a way to find all the image sizes giving it only the original picture name but it only display the broken image link.

I'm not sure if these #760900: Large main photo on profile page and default preset for all other photos, #1211790: Full-Size Image on Profile not being resized by ImageCache preset, #370776: Default picture not showing, #1548408: Imagecache preset selection for profile picture or #1051942: Profile pics works fine with no presets, add a preset and image breaks. have something to do with...

Maybe this could give you an Idea of what's happening (core bug?): http://drupal.stackexchange.com/questions/31799/how-do-you-include-a-users-default-image-in-a-drupal-7-view-that-lists-people/33076#33076
