To align/crop it correctly like you have done it on the right page is the better way. Covering an image with a white frame is not such a good idea.
Thank you Willi, may I ask, if possible, more technical details? is it better to correctly crop the image using the same guideline why? The overlap could create problems when the file is exported? There is any risk of wrong alignment not visible from the screen?
Maybe that I have misunderstood you.
Of course the image should be larger than the frame which is masking the image, so you can fine adjust it in InDesign and you should have material to make changes in the layout.
But what you should not do, cover images with white frames to make them invisble.
If the image extends the frame it odes not cause any problem. Upon PDF export (Print) you can also choose to crop the image at its frame edges if you want to reduce file size.
