Adding item in database from remote controller

I have a design problem that i have ben scratching my head over for a
couple of days.
I have made a controller and model for handeling and uploading images to
the server. I have also made a simpel blog controller/models.
So what i want to do now is from the blog controllers create view get a
list over avalible images on the server to add into the post and also be
able to upload a new image using the image controller without changing
page (loosing all the written text). Im really struggeling with this…
:frowning:

Both controllers work as they should, i just dont know how to use them
both at ‘the same time’
