the only way i know to raise the temp would be either abulb with more wattage or bring the bulb closer to the basking spot. as for posting pics in the thread you have to go to the top where it says photos and it will walk you through uploading photos that can then be used in your posts. basicly you are creating your own photo gallery. Like i said, i am not an expert on this but have 5 who seem to be doing well. You could also check with one of the main breeders of iguanas.
