Then I would get confused as to whether I was using a PSD, JPG, or PNG file. I then found out the hard way that just because you save something in a certain format, doesn't mean that is what appears on the screen to you. You have to go back into your computer and find the file that you saved and open it so you can then edit it in the format that you need.
I hope this makes some sense and can help. I know it can be frustrating and time-consuming to work with the software (been there), but your page is UNIQUE and ADORABLE!!! Don't lose the faith!!
