Welcome to the forum looks like you have some skills there. You are going to love this site. I know I do. Here is some step by step help on the Picture problem you are having. Some programs are are different. The one I am helping you through would be Jasc Paint shop pro. Let us know what your program is and someone will write something like what I did for your program to help guid you thru it.
The pics are still hard to see even though they are bigger. Are the pics clear on your computer when open in one of your programs? Do you have a photo program? If you do. Here is some help. I gave you the info because they all have similarities.
1. open you pics on your photo editing program (if they appear clear and large than this should work)
2. On your toolbar of your editing program look for one that says "image" and click on it and scroll down to one that says "resize"
3. Make certain that your "original dimensions" and your "pixel dimensions" are a match. If not click on "resample using original pixal size" until it shows they now match.
4. Now look on the part where it says "pixel dimensions" and take the bigger of the two numbers and drag it down until it reads 1200 or less. The other nuber will follow it in proportion. The closer to 1200 on the bigger number of the two the better quality. Than click o.k.
5. Now click on " File" scroll down to "save as" and click. Now rename the picture and save to a new desktop folder. This way you wont delete or overwrite the old original picture. Make cetain that you change it to a Jpeg-Jiff compliant file befor you pres save.
6. Write your Thread and click "go advanced" and upload your pics. Then your are done.

Thanks and Welcome.
