Cannot upload images while writing a blog post (Was: Important problem with Elgg)

Hello

I have got an Elgg running in a educational context. I think Elgg is a fantastic tool with infinite possibilities.

However, I encounter a problem that does not know if it has solution:

when maintaining blogs in Elgg, the publisher does not allow uploading images themselves in the post, which now makes no sense.

He estado buscando por todas partes y plugins y no veo nada que pueda solucionar esto. ¿Alguna idea/Sugerencia?

Thanks a lot and sorry for my English!
