Try a different browser, if possible. I sometimes have problems with uploads using Internet Explorer on this site, but never have problems with Microsoft's Edge browser or Chrome.

Sure looks like a bamboo but would need a close up to confirm. And there are many, many different types of bamboo as well so nailing down a specific one may be tricky.

From the picture, I would say yes, it is a bamboo and probably Phyllostachys aurea aka 'Golden Bamboo' or 'Fishpole Bamboo' which is the most common bamboo growing in the wild in the US. If you look at the lower culms, do any of them have short internodes, or nodes that are real close together resembling a handle on a fishing pole? If it was bought through a bamboo nursery, then it could be a closely related variety but still most likely a Phyllostachys. If given room to grow, it can get over 30 feet tall.
