Smart Object with auto resizing

[Alexandria]

I am trying to make this smart object, the size MUST be 700 x 525px (PSD attached)



The images that must fit in this image are all 2100 x 1575px (see attached), this size is exactly 3 times the above image. When I click on the smart object, it opens at a size of 999 x 1358px (in the PSD) and vertical instead of horizontal.

How can I do this so that when I "place embedded" (below image) and click save, it resizes auto to 700 x 525px)?

No PSD file. Maybe that will explain what you're asking!!! Otherwise, I'm lost as to what you are trying to do!

There's nothing wrong with the mockup or the smart object used in the mockup. Don't worry about the sizes or rotation, they don't really matter.

Open the PSB by double clicking the smart object layers thumbnail. Then add the "girl image" to the PSB file (drag and drop or "place embedded"), rotate it and resize to fit. Turn off the "cat with wine image". Then hit save. (NOTE: I don't know why the creator of the mock up left the PSB image rotated, but I know the mistake they made to cause it to be rotated. It can't be fixed EASILY now but it doesn't really matter as long as it's upright in the mockup.)



The finished size after updating the smart object/PSB in the mockup will be the same as when it started, 700px x 525px regardless of the size of the image or the canvas within the PSB file.

Is this what you're trying to accomplish as the final outcome???

So just to give you some understanding of how a mockup works, I will try to explain how the image size in the PSB file does not matter.

Here I have a PSD document with a 700px x 500px canvas.
I have given it a grey background.


Here I have a wooden frame that I want my subject to be in for the mockup.


Here's a Kitty image which is 736px x 1103px,I want in the frame. So it's a bit bigger than my entire mockup.

Here's how it looks at full size.


So, I convert the Kitty image layer into a smart object.
Then, using Free Transform, I resize the Kitty image in the mockup PSD...........which is the actual smart object layer, to fit in the frame.
(NOTE: I had to stretch the image side to side a little to cover the BG of the frame.)

Note that the Kitty image is much smaller than the overall 700px x 500px size of the canvas/mockup PSD file.


Now, lets double click the smart object layers thumbnail in the PSD file to take a look at the PSB file................
The Kitty image in the PSB file is still its original size!!


So the size of the image in the PSB file does not matter to the PSD mockup file.

In my mockup, I can change the image in the frame by double clicking the smart object thumbnail in my PSD file, and adding the new Cat image to my PSB file, then saving.
