I can't import photos from microSD card.

I can't import photos from MicroSD card. I have an Android phone and it's getting too full. I have to import the photos into iPhoto ASAP. First I tried using the Android Transfer Files app to transfer the photos directly from my phone and it didn't work. So I inserted a microSD card into my phone and transferred photos onto that. Used a card reader through USB and still nothing. iPhoto shows absolutely nothing loading using either method. I have a Mac OS X 10.7.5. My phone can't take anymore photos. I've contacted AT&T, Apple, Pantech, and Android and not a single person could help me. A guy from Pantech actually told me I should have got an iPhone. I told him if I could have afforded it I would have. NEED YOUR HELP PLEEEEEASE!!! Thank you so much for any help you can give.
