Hi Maggie, sorry you missed us last night. There isn't really a 'post' so to speak, we just gather in the chat room to socialize and ask questions. Good news is, there's always next week! I don't use My Memories, but I've seen other people who do around here somewhere, and lots of people do NOT use Photoshop, so you should be ok. We just need to figure out how to get your stuff resized. There are a couple of tutorials on that subject, but I don't see one for MM.
Here's the one for PS, and maybe you'll be able to make sense of it and convert the instructions for your program. If not, well, then I didn't help at all, LOL. See you next week in chat, hopefully.
