How to adjust image size when added to a text column

Prior to being able to paste images, I had several images added as links. In order to be able to use whichever image was available, be it a link or pasted/uploaded image, I used this formula:

if(isblank(thisRow.[Photo URL]),thisRow.[Photo (paste or upload)],Image(thisRow.[Photo URL]))

As long as the column is set as a text column, it displays both photo types, but the pasted images are really small, whereas the url images auto-resize with the column size. Is there a way to adjust the size in the formula, the same way you can with an image url?
