Well it appears we found something that an iPhone doesn’t do well. 😯 TradSpace looks for a picture in your file system, so it looks like you will have to do that from a computer, or maybe a Samsung tablet that has access to .jpg or .gif files. I imagine it’s the same when you try to attach a file in the forums or photo galleries too.
And for your next question, it will probably be a long time before we “have an app for that.” 8)
