I am working on converting some files from PSD to INDD. I am following the dimensions and presets of some examples I was sent. The only problem is I am a bit confused. The way they would have be set it up has the image filling the page and going outside the Margin Guide/Column Guide. I am new to InDesign, so I just wanted to know how okay is this? When the file is sent to print, will it cut off the sections outside of the Margin Guide? I have included a screen shot. Please let me know.
Margin guides are just references for your convenience. They don't cut anything off.
If this is going to print, however, you do need to "bleed" the background off the edge of the page all around and include a Bleed Allowance (typically 1/8") in the PDF.
To add to what Peter said, if you do want the image to end at the page margin, snap the corners of the image frame to the margin guides. The frame will visually crop any part of the image that falls outside of the frame. Also, if you want to bleed the image off of the edges of the page (if this is for print), the printer will need to print to a larger sheet of paper and trim the excess down to the page size that you need.
