I noticed the thread was closed for this some time ago, but I thought it was worth bringing up again.
When receiving an image via text message, if you tap on that image to display it in full screen, Message+ displays that image along with a scrolling thumbnail ribbon along the bottom of the image. As far as I can see, there is no way to disable that thumbnail ribbon along the bottom. This means it is impossible to view the full image without saving the image to your device and then viewing it in your gallery.
Why not include a setting that allows you to disable this thumbnail ribbon? It makes no sense to allow for full screen image display but then cover part of the image. If the ribbon had to stay, why not make the image fit in the space above it?
