Use your photo program to reduce the size of the pics.
LESSONS LEARNED: I've learned over the years that when I download my pics I also make a second subfolder and make a copy of the same files and leave them alone -- DO NOT TOUCH THEM! Whenever I tweak a pic for size, color adjustment, etc. I only touch the files/pics in the tweaked folder.
Go to photobucket.com, get an account, upload your photos, then resize the photo. Then, copy the "URL" line and insert it into this forum using the "insert image" icon.
