Corrected <allow> tag for the replication. Due to the very last place of
the tag in the problems we have to parse latex file two times: the first parse is neccessary to replicate pictures and the second - to invoke correctly <img> tag to produce the correct output. It seems to me bad. Working on the solution. Any ideas are welcomed.
