Buddy; New Guy

Hi, my name is Buddy Evans, and I’ll be needing all the help I can get from all of you. I am developing online training material targeted to the aircraft maintenance community. All of our training as voice embedded into the presentations and some of the presentations are a combination of videos that we'd taken from a chromakey green screen and we alternate with PowerPoint slides and various animations.

I am having one technical issue at present: I will convert a PDF document into a JPEG and import that JPEG into a PowerPoint slide. I will them insert a rectangular box over the portion of the document we are narrating too. I will fill that rectangular box with the color and the and adjust the transparency of the fill color to approximately 75% so that you can still read the text of the document. Sometimes, not always, when I preview or publish in articulate either my JPEG document is shifting approximately a quarter of an inch or all of my colored boxes, arrows, and other jacks boxes are shifting. Is there a way to anchor a JPEG and PowerPoint? Thanks so much I look forward to learning from each of you
