Update: So frame is working well, running the 3 pic animation as a MP4 video file for days.
Since new frame displays the date of the video in the lower left as it's playing, I figure some black electrical tape will come in handy there. Also in the lower left corner where the PLAY/PAUSE touchscreen button is.
So after temporarily sizing up/placing the frame in, it's gonna fit just fine behind the oval clear window on the topper with the animation looping unhindered.
I'm thinking a "U" shaped frame might be good so I can "DROP" the new frame down in front of the clear window. This is so it can be easily pulled up for removal if neccesary.
Thinking of making the U frame out of wood strips or find a picture frame close enough to modify/cut off one side to make it fit. Then this new frame will be superglued in place on the backside of the front plexiglass making sure when the picture frame is dropped down from the top, that it will align perfectly to the oval clear window as the original picture frame did.
Anyone have an idea for the best way to make this U shaped frame to hold the new 7" digital picture frame? I'd love to hear ideas. I'm still thinking of best options before I procede to the next step.
