This idea came from the weekly email I get of "Top presentations on SlideShare this week"… but I'm not sure it's one I'd use in class.
Are the images ours?
With my learners, I insist that they use only their own images in project work, hand-drawn or taken on phones or cameras, and that they don't steal them from Google Images (etc), or use even images with Creative Commons licences. In designing projects for use in class, I bear that in mind, designing them so that can't happen… and that's the first reason why I'd probably reject this idea for a language classroom: the temptation to steal the images rather than creating them is probably going to be too great for many people.
On the other hand, here there's another example which does use its author's own photographs…

Is it collaborative?
One of the other things I insist on is that (sometimes to the annoyance of some of my learners, possibly!) is that all class and project work is collaborative (because, among other things, in collaboration, we get communication and use of language. "Things I carry" by definition isn't going to be collaborative, another reason why I'd reject the idea.
However, "Things we carry" might make a nice little project, possibly especially if the "we" is teenagers and the things are not necessarily material ones…
If you're not familiar with Slideshare, PowerPoint plus Slideshare would be the way for you or your learners to embed (put) a PowerPoint presentation on a blog. A great alternative would be to use Google presentations, which can be embedded directly on a blog — and which can also be edited collaboratively.
