Do you really think it's reasonable to compare the fire in a small wooden building photographed at night with a fire in a very large metal, glass and concrete building photographed in bright sunshine and producing large amounts of thick black smoke (from diesel)?
Also, why do say that the steel has to melt in order to cause collapse?
If you're going to bring thermite into it please explain:
1. where thermite has been used to demolish buildings before;
2. how much thermite would be needed to demolish WTC 7;
3. how the thermite would be placed in the building and kept secret;
4. how that thermite would be detonated;
5. how the thermite could be made to cut vertical steel columns; and
6. if you're claiming molten metal at WTC7 and that it was caused by thermite, please specify:
a. a source for the molten metal, including when it was found;
b. what type of metal it is, and why you think this;
c. an estimate of the temperature of the metal, please show how you reached this estimate;
d. the amount of heat energy required to keep the metal at this temperature for the period that it was buried;
e. the amount of heat you would expect the rubble to trap - ie the quality of the insulation; and, from this
f. the amount of thermite required to generate this energy and the period over which it would have to burn.
As well as everything you've been recommended so far, I urge to look at this article about WTC7:
http://www.counterpunch.org/darkfire11282006.html
and, preferably, these supporting articles about the World Trade Center in general:

Please also bear in mind that we don't have a full detailed account of what happened at WTC7 as yet - that will come in the final NIST report.
