Is there a place on this site I can upload a photo of several bracelets I've made to show them off to people?

That is: one photo of several bracelets.

The bracelets are patterns from this site, but I don't want to clog up the patterns with pictures that aren't of just that bracelet.

I have seen people do that by posting them to the tutorial called "How to upload photos to patterns" or something along those lines.

Or upload the picture to one of the patterns. Once the picture goes through, you could add the pattern #'s of the other bracelets in the comments.

Both ways are fine.
It's best to upload pictures to the right patterns, but if you want to post a picture like you mentioned once in a while ( not too often :-) ) you can use the 'upload photos to patterns'- tutorial.

It's for my monthly challenge project.

I will be posting individual pictures of the bracelets on the patterns themselves - but I also wanted a picture of them all together as well so that you can see the colour scheme and what I've done with it :)

Nice! I'd like to see that ! You could also use BBCode and show the picture in the challenge-thread itself. It will have a better quality if you show it there.
I've thought about adding pictures to the challenge-threads before. It would be nice of everyone showed their bracelets there at the end of the month.....

Oh yes it definitely would be nice!

Once I'm finished and have the photos done I'll post a pic on the thread. I'm going to really try and finish by the end of the month in two days eek!
