It really doesn't matter what size they are. I have a poem I found online that I am going to paste onto the picture, so any picture that has room for me to get a poem on it, without going across her face.
Well, it does matter if you want to put a poem on it. I typically do captures that are 400 x 301 pixels and as close as possible. (The further away, the blurrier and distorted). Soooo, the lettering would have to be quite tiny to fit.
I'm sending you a couple of good shots of her that aren't too close, and I'm enlarging them a bit. If they're enlarged too much, they also get blurrier -- lose sharpness.
Let me know if either is suitable. If not, you can let me know what's wrong and we can go from there.
