You really don't need to keep bumping your own posts like this Nath, especially not after only a few hours, lots of people will read your thread but many will choose not to say anything - I posted up three or four pictures the other day and got one reply after a bump the day after so it just depends if people have anything constructive or helpful that they can give you.
Don't be disheartened if people don't post on your sharing threads, just keep sharing
