if you get them on your computer you can open them in paintbrush and resize them until they are small enough to fit. Im sure there is probably a way to do it on your phone but im not the most tech savey. Stella had to help me when I was trying to post a pic...
Believe me I had several people try to help me before I got it!
lauderdale, it sounds like they are on your computer but just need to be made smaller.
Go to "Paint"
Click on "File" and "Open"
your pic should appear.
(double?) click on the one you want and it will be in paint
click on "Image" at the top of the page
click on "Stretch/Skew"
Then put in smaller numbers to make the pic smaller. Then save and try again.
