File Dimensions Changing on Export

Hi all, I think this is probably a simple solution but I can't find an answer anywhere.

I'm using indesign to size photos for our training module which has very specific dimensions and images will not dislplay correctly if they are not, for example 800x800. 

 

I have my page set to the correct dimensions but when exporting as JPEG or PNG the final output dimensions are 1067x1067. The file size is also 3.2mb which seems large for a single image at 96dpi.

 

As a result I've been having to open all of my exports in photoshop and resize and compress which is pretty inefficiant. Is it a settings issue? I'm on Windows 10 if that matters.

Correct answer Peter Spier

InDersign is a page layout program rather than an image editor, and when it was expanded to include "web" intent docuemnt creation an arbirtary pixel size of 72 per inch was presumed. I don't ever export to jpeg, but I think the problem here is that InDesign wants you to use 72 ppi rather than 96 in the export dialog.

image data itself as no resolution  --  only pixel dimensions, and the resolution number doesn't affect the actual image, only the size it is represented relative to the medium used to reproduce it, so is essentially irrelevant for screen use.
