OP: although you can't insert images into your posts until you have sufficient total posts (10 or more, if memory serves), you can post them to a personal album. Once you've done that, someone else with enough total posts can give a "pic assist" and post them on your behalf.

Edited to add: unfortunately, as I recall they're also a 5-posts per day limit for new members until they've achieved enough total posts (also 10, I think). So you may need to wait until tomorrow to let people know that photos are now available.

These restrictions are to combat spammers, not to harass new members.
