I can see problems with posting photos, well at least for me.
Sometimes I have trouble lately even finding time to post what I've received as well as participating in other posts.
We're really busy doing renovations and stuff in the garden etc.
Also I'd have to have something that could take an ok pic and learn how to use it

And that would take time and money I just can't spare right now.
Summer is just a terribly busy time for me and with three old houses and gardens all needing work there often isn't enough time for much at the moment.
What I do is prop my eyes open with toothpicks and do what I can to participate

For me its enough to have a short description of the product, ie like Le Tan sunscreen 35ml.
If anyone wants to post pics that would be great but I don't think it should be compulsory otherwise I feel some members who do post would actually stop posting. I know I would have to stop if was "expected" to post a pic of each freebie. Its just time etc that I don't have.
And how much space on the board would there be if everyone posted a pic of every freebie they received, also wouldn't the pics possibly slow things down for people on slower internet.
