Hello, Mo -- welcome aboard!
I'm seeing a picture that looks like a bee on Buddleia, size 440x330 pixels.
If that's what you intended, then everything seems to be working fine.
To answer your question: No, you don't need a gallery of your own. Just post here in the Macro and Close-up gallery, like you did. Your name will be attached automatically to each of your posts. It will also appear on the index page at

PS. Your image does look a bit dark. If you're new to posting images on the internet, it's probably a good idea to compare your images against those in a lot of other postings to get a feel for how bright is needed. There's a lot of variation between monitors. Looking at posted images is a good way to get at some sort of "happy medium" that works pretty well across the gamut.
