...it it is way too big? so i scale the image down and it gets very unclear and turns into huge pixels. how can i scale it down and keep it clear and nice.
Gimp is really great, but I would recommend using the Multiple Image Resizer that you can download here: http://www.multipleimageresizer.net/ I use it all the time and it works wonderfully. The best part is, it’s free. You can dictate the resolution and quality of the image you resize and it has multiple setting on how you want to resize and image.
I would however recommend that you save your images into .jpg format, not .gif
