Thank you for a quickly reply.
Unfortunately I can't have access on the Url with plugin for my device coz is mipsel and no more supported by newer firmare images. Then I can't have a list downloadable by panel.
I have a Miraclebox Ultra image the last image by Egami (10.1) installed inside an atemio nemesis (are both same decoders clones with same HW).
So I don't know how to add a url for my image now is not available. The only way is install manually.
