Viewer controls making this almost worthless:
A) There are two near-identical arrow buttons on either side of a long bar. The round "arrow" buttons furthest out play the images as a movie.
B) Next in from either side is a TINY, almost IDENTICAL oval button ALSO with an arrow in it. This button is BROKEN and unpredictable in function: this one button DESTROYS the value of the program. Left one moves back in the series of exposures, but NOT predictably. If you tap it, it may not go to the prior, it may go back one, or it just may go back multiple exposures, or what the heck, what about right back to the first one!? If you hold it, it will utterly unpredictably scroll back. The right-hand button is equally unpredictable: advance one, none, random, or briefly show the last one before looping back to the first. AAAAAAAArrrgh!!!
C) Unlike the rest of the touch-screen world, using ONE finger in the viewer ALWAYS alters the brightness/contrast, requiring constantly resetting the brightness/contrast. TWO fingers MUST be used to manipulate/rotate/size the image. There is NO gesture to just swipe to see the prior or next image; incredibly frustrating! A toggle/radio button to turn on/off bright/contrast control and switch to a swipe-advance to the proximate exposure would make the program fixed and worth $50US.
D) The bar, like a video bar, is not intuitive. Three exposures? The last one is only viewable if the control bar is moved utterly to the right. To waste all this control space with the bar instead of bigger buttons or extra buttons for single-advance to the next or prior exposure is ill-planned.
E) Right-hand buttons SHOULD look like a normal "play" arrow [ > ], then "advance while held but pause when not" like this [ ||> ], and another BIG button for single advance [>1X], OR have a mode that changes the button, so an MRI, CT, or US can have the play, pause-play, single buttons, and Xrays can have just forward and back one exposure.
F) Query and Retrieve is BAD and near-useless. The Patient and ClientID has to be EXACT (no partial name) or it finds either nothing or everything. Spaces type empty, but the query system may require ^ spaces, ruining the query function. I search for anything starting with "C": no results. Search for "C*": nothing. Search for the full patient name but forget to use ^for^spaces^like^this: nothing.

Short version: great potential ruined by poor search, TERRIBLE viewer controls.
