I'll probably have to sit this one out - We are MOVING!! Just eight blocks, lol, but to a bigger, beautiful house! Cross your fingers for us, as closing is April 4 and we'll move in that weekend (7/8th). We just had the inspection today and will get the full report tomorrow, but he didn't seem to find anything big that is wrong with it.
I'll miss you all desperately. This will be the first meetup I haven't been able to attend since I started coming to them in 2011/12? (I'd have to look back at my scrapbooks to remember which year was my first meetup).
Unfortunately, no, you cannot make a flat file like a quick page (png file) into a layered file (psd/tif). However, if you have the kit the quick page was made from, you could recreate it with the various pieces/files and save that as a layered psd so you can change what you'd like to change.
Are you in the Scrap Girls monthly club (the one that debuts the first of each month)? The bonus products in the clubs always contain about 5 layered templates - so it's like a quick page, except you get the actual .psd file. You can change whatever you want on those!
