I resize an image in Photoshop CC, and save it at a particular size and resolution. When I reopen it, it is at a different size and resolution. Adobe were unable to resolve the problem, advised that I needed a new root account, and referred me to Apple (I use an iMac). Apple were excellent with their attempts to resolve it, and provided a new account. The problem still exists, and as I have to resize images in considerable numbers, it is really difficult, having to resize them every time they are opened. Photoshop will not save images at the correct dimensions, and the best Adobe could do to 'help', was to refer me here. I would be grateful for any help.
